数学笔记

Complex numbers are more natural than real numbers or quaternions because complex numbers have simpler nondegenerate quadratic forms: {$Q(u)=u_1^2+u_2^2+\cdots +u_n^2$}. For we can insert a scalar {$i$} and that converts any minus sign into a plus sign.

Laws of form

  • Concatenation is "saying". Saying multiple times is the same as saying once. {$a^2=a$}.
  • Cross is negating. It is crossing. Negating twice is identity. {$b^2=1$}.
  • We can have a different kind of negating or a different kind of negated for which negating twice is reversal. {$c^2=-1$}

Auxiliary loops in space-time are compatible with the rays in space-time, perhaps in this way the mind is compatible with the brain. That might be relevant for the hierarchy of agency.

Grammar of sociology in terms of a pattern language grounding concepts such as "generation", "the right biography", "class", "both agressors lose".

Groups and symmetries. From finite groups to Lie groups.

Geometry arises on a vector space when we place a quadratic form on it, {$Q:V\rightarrow K$}. It gives a notion of length of a vector because {$Q(av)=a^2Q(v)$}, and also a notion of distance because there is a symmetric bilinear form {$B(v,w)=\frac{1}{2}(Q(v+w)-Q(v)-Q(w))$}.

Equivalence up to isomorphism is relevant for "user requirements" as opposed to "material implementation". This is relevant for Bott periodicity.

In Lie group for rotations, SO(3), the bracket of [x,y] gives you z.

In choice frameworks, such as the simplex, the center is the basis for geometry and the vertices are the basis for matter. Together can they ground general relativity?

I dreamed of the grouping of examples from branches of mathematics by considering whether they involve, for example, aspects of mathematics, logic, semantics, and so on.

Minkowski space. Time {$-t^2$} has us step out (thus reversing direction), space {$x^2+y^2+z^2$} has us step in.

Why doesn't adding a pair of generators {$a_1 b_1$} to a Clifford algebra change it?

Generators {$a_j$} for which {$a_j^2=1$} are experienced directly whereas generators {$b_j$} for which {$b_j^2=-1$} express the change in direction upon reflection, thus stepped out.

  • Modeling agency
  • Improving a model of the environment = Bayesian prior.
  • Controller gets new information and also the system changes over time.
  • Don't care about the previous states, just the prior (t) and the current issue (t+1)
  • Kalman filter: when the prior is a Gaussian then the posterior is also a Gaussian
  • So only the means and variances need to be stored

  • Unifilar generator. A generator is unifilar if it is deterministic given output. They form a separate category.
  • Forgetful functor: Unifilar Generator to Generator. In BorelStoch this has a right adjoint.
  • Usually forgetful functor has a left (free) adjoint. A right adjoint of a forgetful functor is cofree. In this case the forgetful functor is forgetting both a fact about the objects and the morphisms.
  • How does this relate to lenses?
  • Strongly representable Markov categories are cool.
  • Epistemic model and dynamical model. You want your model of the system to be unified.

Conformal and analytic is the same.

Energy can be defined as the "separation constant" in Schroedinger's equation. If we can separate the wave function into a time dependent function and a position dependent function, then we can segregate the two sides of the equation so that one side depends on time, the other side depends on position, and both sides are constant, and that constant is the energy.

Visual frameworks

  • Visual frameworks connects visualization with semantic contexts such as gravity. Note that gravity is based on a quadratic power law and yields the fivefold conics.

Absolutism based on relativism is good. Relativism based on absolutism is bad. Objectivity based on subjectivity is good. Subjectivity based on objectivity is bad. The mind that does not know is based on the mind that knows and not the other way around. This is the rule of consciousness and the basis for morality.

There is a gap between the quantum ether (the quantum foam) and the waves that propagate through it. Particles don't exist, particles are the medium. Waves exist in the medium.

Threesome

  • Vector bundles. Jimmy told me about vector bundles having a threefold sense: Data, gluing, and 3 sets coming together. This happens in 1 degree, 2 degrees, 3 degrees.

Folk psychology. Daniel Dennett suggested studying this. Contact him.

In the book on interpretations of quantum mechanics, there is the question of what is real. For example, in electromagnetism, the gauge can be adjusted by adding any gradient. This can change whether the change is transmitted by the speed of light or whether that speed is infinite and it happens instantaneously. But these two scenarios also raise the question of the reality of the "wiggle". What is real is a moral choice. Is the medium real? Or is the wiggling real? The wiggling creates the wave that moves across the medium. The medium is made of particles and anti-particles that appear from the foam.

Applying a boundary map twice gives zero. Applying it twice removes two vertices, and this can be done in different orders, yielding different signs, canceling out.

For the Snake Lemma, add a zero vector space before the first kernel and add a zero vector space after the last cokernel. Then we have the eightfold way with seven mappings.

Can large language models work by simply transforming existing input - taken to be grammatical - to preserve grammaticality.

Choice Frameworks

  • A category with a zero object has semantic symmetry with regard to choice frameworks. A category without a zero object, but with initial objects and terminal objects which differ, such as the categories Set or Cat, have syntactic asymmetry.

Physics

In the Standard Model, fermions are not their own antiparticles, but in some theories they can be. Among other things, this involves the question of whether the relevant spinor representations of the groups Spin(p,q) are complex, real (‘Majorana spinors’) or quaternionic (‘pseudo-Majorana spinors’). The options are well-understood, and follow a nice pattern depending on the dimension and signature of spacetime modulo 8.

Cube reflections given by vectors u, v, w from the center of the cube to the center of a face, the center of an edge, and the center of another edge.

"belt trick", aka the "Dirac scissors" or "Balinese candle dance

When two events happen (the measurement of spins) there is a frame where one happens before the other. So if they are causally connected (as with spin measurements) there needs to be a distinguished frame. But that could be the frame in which they were initially entangled. So entanglement posits the existence of such a distinguished frame.

Path integrals depend on the number of points in space, or the number of interactions. But my approach suggests that this number is actually given by the degree of x in the relevant polynomial.

Quantum computing

Amelia: [The axiom of function extensionality is] inconsistent with many axioms of a more "computational" nature. For example, "formal Church's thesis" says that for any function N→N, there is a "program" (we call it a realizer) that realizes it. You can kinda see what goes wrong: this would be able to tell e.g. "λ x → x" and "λ x → x + 0" apart. You could imagine an assignment of realizers that sidesteps this, though, so to see that it's actually inconsistent takes slightly more work.
