If there is a zero in the Riemann function's zone, then there is a function that it can't mimic? į:
If there is a zero in the Riemann function's zone, then there is a function that it can't mimic? At the level of forms, this can be seen by decomposing a Hermitian form into its real and imaginary parts: the real part is symmetric (orthogonal), and the imaginary part is skewsymmetric (symplectic)—and these are related by the complex structure (which is the compatibility). 2019 liepos 10 d., 16:52

Note that given a chain of perspectives, the possibilities for branching are highly limited, as they are with Dynkin diagrams. Arnold  "Polymathematics: complexification, symplectification and all that " 1998 video. 18:50 About his trinity, his idea: "This idea, how to apply it, and the examples that I shall discuss even, are not formalized. The theory that I will describe today is not a conjecture, not a theorem, not a definition, it is some kind of religion. I shall show you examples and in these examples, it works. So I was able, using this religion, to find correct guesses, and to find correct conjectures. And then I was able to work years or months trying to prove them. And in some cases, I was able to prove them. In other cases, other people were finally able to prove them. In other cases other people were able to prove them. But to guess these conjectures without this religion would, I think, be impossible. So what I would like to explain to you is just this nonformalized part of it. I am perhaps too old to formalize it but maybe someone who one day finds the axioms and makes a definition from the general construction from the examples that I shall describe."

The root systems are ways of linking perspectives. They may represent the operations. {$A_n$} is +0, and the others are +1, +2, +3. There can only be one operation at a time. And the exceptional root systems operate on these four operations. Real forms  Satake diagrams  are like being stepped into a perspective (from some perspective within a chain). An odddimensional real orthogonal case is steppedin and evendimensional is stepped out. Complex case combines the two, and quaternion case combines them yet again. For consciousness.

If SU(0) is R, then the real line is zero, and we have projective geometry for the simplexes. So the geometry is determined by the definition of M(0). {$SL(n)$} is not compact, which means that it goes off to infinity. It is like the totality. We have to restrict it, which yields {$A_n$}.

If we think of rotation by i as relating two dimensions, then {$i^2$} takes a dimension to its negative. So that is helpful when we are thinking of the "extra" distinguished dimensions (1). And if that dimension is attributed to a line, then this interpretation reflects along that line. But when we compare rotations as such, then we are not comparing lines, but rather rotations. In this case if we perform an entire rotation, then we flip the rotations for that other dimension that we have rotated about. So this means that the relation between rotations as such is very different than the relation with the isolated distinguised dimension. The relations between rotations is such is, I think, given by {$A_n$} whereas the distinguished dimension is an extra dimension which gets represented, I think, in terms of {$B_n$}, as the short root. į:

Usually multiplication by i is identified with a rotation of 90 degrees. However, we can instead identify it with a rotation of 180 degrees if we consider, as in the case of spinors, that the first time around it adds a sign of 1, and it needs to go around twice in order to establish a sign of +1. This is the definition that makes spin composition work in three dimensions, for the quaternions. The usual geometric interpretation of complex numbers is then a particular reinterpretation that is possible but not canonical. Rotation gets you on the other side of the page. į:

Partial derivative  formal (explicit) based on change in variable, total derivative  actual (implicit) based on change in value. Measurement (crucial in physics) can be defined in terms of covectors, as being dual to vectors. Covectors can be thought to point in the same direction as vectors  they are complements of each other with regard to the inner product. This duality is thus fundamental to the concept of measurement. The vector and the covector divide a scalar field into its local variation (given by the vector) and its global scaling (given by the covector) which together give the value of the scalar. Thus vector and covector define the duality of local and global extremes which come together as the scalar field. A vector is 1dimensional (and its dimension) and its covector is n1 dimensional (it is normal to the vector). In this sense they complement each other. Vectors are described in terms of partial derivatives (based on the local coordinate systems) whereas covectors are described in terms of (total) forms dx. Ištrinta 28 eilutė:

Symmetry group consists of distinguishable actions which accomplish nothing Taylor series for e^x is based on the symmetric function (inverted)  it is the basis for symmetry in analysis. When we measure spin  we impose the spin axis we are expecting  but that is an imposition of expectations related to the "waiting" that I am modeling. Also, how is that waiting related to emotional life and expectations? Comparing measurements yields "information" and it may be information which is limited by the speed of time. Is manyworlds theory the flipside of leastaction ? Chess pieces (rooks, bishops, knights) move in very basic ways that bring to mind root systems and especially the geometries that they open up in the gap they create by being more complex e_i  e_j than the generic basis e_i. Lie algebras (root systems) are the cracks or gaps between coordinate system layers. The "higher energy" a system has, the bigger the crack, the more possibility for variation and freedom, how the system will develop or degenerate. The lowest energy system is the one that has the roots e_i (and its byproducts, e_ie_j, e_i+e_j etc.) because everything is explicit. And the highest energy system is A_n, given by e_ie_j, because the e_i are implicitly latent. The root systems, as a minimum, have to contain the e_i  e_j because they encode the Lie bracket of the e_i. The question is, what are the ways that they can be expanded? First, a dual encoding can be given e_i + e_j. And the two must then be related in one of the various ways. The combinatorial interpretation of nchoosek counts placements = "external arrangements" n! x...x (nk+1)! and then divides by the redundancies = "internal arrangements" k! Thus it relates external and internal (within subsystem). Entanglement  particle and antiparticle are in the same place and time  and they have the same clock and coordinates į:

Momentum can be attributed to an individual particle (as its change) but it can also be attributed to the entire system (as its change). And also, changing the momentum of a particular particle can change when (and whether) we will come to a particular state of the system. In particular, the particles are interconnected and so that makes for a complicated relation between the time evolution of each particle (in terms of its position) and the time evolution of the system. This can be compared to a computer program which may change the order of its instructions. į:

Duality breaking allows that God is good and not bad. Because we want to break the duality of good and bad, increasing and decreasing slack. Orientation is a complete, absolute, total distinction between inside and outside, their complete segregation and isolation. (In contrast to the yinyang symbol.) SO it is highly tenuous  it can break at any single point  but it can eternally grow more weighty. į:

Gap between structures, within a restructuring, is a "hole", and so methods of homology should be relevant. How does cohomology relate to holes? If we consider the complement of a topological space, what can we know about it? For example, if it is not connected, then surfaces are orientable. 2016 gruodžio 15 d., 17:06

A punctured sphere may not distinguish between its inside and outside. And yet if that sphere gets stretched to an infinite plane, then it does distinguish between one side and the other. 2016 liepos 04 d., 17:20

Time: A moving point is a line, a moving line is a plane, a moving plane is a volume... Time is the addition of a scalar (from a field), thus the addition of choice. Time relates affine and projective space. Compare time with space. į:

Time relates affine and projective space. Compare time with space. A moving "center" is a point: the center is what moves, thus what has time. 2016 liepos 04 d., 17:19
