Is analysis as a cognitive process analogous to particle reaction?

The latest work with number theoretical aspects of M⁸-H duality (see this) was related to the question whether it allows and in fact implies Fourier analysis in number theoretical universal manner at the level of H= M⁴× CP₂.

The problem is that at the level of M⁸ analogous to momentum space polynomials define the space-time surfaces and number theoretically periodic functions are not a natural or even possible basis. At the level of H the space-time surfaces can be regarded orbits of 3-surfaces representing particles and are dynamical so that Fourier analysis is natural.

That this is the case, is suggested by the fact that M⁸-H duality maps normal spaces of space-time surface to points of CP₂. Normal space is essentially the velocity space for surface deformations normal to the surface, which define the dynamical degrees of freedom by general coordinate invariance. Therefore dynamics enters to the picture. It turns out that the conjecture finds support.

Consider now the topic of this posting. Number theoretic vision about TGD is forced by the need to to describe the correlates of cognition. It is not totally surprising that these considerations lead to new insights related to the notion of cognitive measurement involving a cascade of measurements in the group algebra of Galois group as a possible model for analysis as a cognitive process (see this, this and this).

1. The dimension n of the extension of rationals as the degree of the polynomial P=P_n1∘ P_n2∘ ... is the product of degrees of degrees n_i: n=∏_in_i and one has a hierarchy of Galois groups G_i associated with P_ni∘.... G_i+1 is a normal subgroup of G_i so that the coset space H_i=G_i/G_i+1 is a group of order n_i. The groups H_i are simple and do not have this kind of decomposition: simple finite groups appearing as building bricks of finite groups are classified. Simple groups are primes for finite groups.
2. The wave function in group algebra L(G) of Galois group G of P has a representation as an entangled state in the product of simple group algebras L(H_i). Since the Galois groups act on the space-time surfaces in M⁸ they do so also in H. One obtains wave functions in the space of space-time surfaces. G has decomposition to a product (not Cartesian in general) of simple groups. In the same manner, L(G) has a representation of entangled states assignable to L(H_i) (see this and this).

1. Cognitive measurement would reduce the entanglement between L(H₁) and L(H₂), the between L(H₂) and L(H₃) and so on. The outcome would be an unentangled product of wave functions in L(H_i) in the product L(H₁)× L(H₂)× .... This cascade of cognitive measurements has an interpretation as a quantum correlate for analysis as factorization of a Galois group to its prime factors defined by simple Galois groups. Similar interpretation applies in M⁴ degrees of freedom.
2. This decomposition could correspond to a replacement of P with a product ∏_i P_i of polynomials with degrees n= n₁n₂..., which is irreducible and defines a union of separate surfaces without any correlations. This process is very much analogous to analysis.
3. The analysis cannot occur for simple Galois groups associated with extensions having no decomposition to simpler extensions. They could be regarded as correlates for irreducible primal ideas. In Eastern philosophies the notion of state empty of thoughts could correspond to these cognitive states in which SSFRs cannot occur.
4. An analogous process should make sense also in the gravitational sector and would mean the splitting of K=n_A appearing as a factor n_gr=Kp to prime factors so that the sizes of CDs involved with the resulting structure would be reduced. Note that ep(1/K) is the root of e defining the trascdental infinite-D extension rationals which has finite dimension Kp for p-adic number field Q_p. This process would reduce to a simultaneous measurement cascade in hyperbolic and trigonometric Abelian extensions. The IR cutoffs having interpretation as coherence lengths would decrease in the process as expected. Nature would be performing ordinary prime factorization in the gravitational degrees of freedom.

1. For the algebraic EQs, the geometric description would be as a decay of n-sheeted 4-surface with respect to M⁴ to a union of n_i-sheeted 4-surfaces by SSFRs. This would take place for flux tubes mediating all kinds of interactions.

   In gravitational degrees of freedom, that is for trascendental EQs, the states with n_gr=Kp having bundles of Kp flux tubes would deca to flux tubes bundles of n_gr,i=K_ip, where K_i is a prime dividing K. The quantity log(K) would be conserved in the process and is analogous to the corresponding conserved quantity in arithmetic quantum field theories and relates to the notion of infinite prime inspired by TGD \citeallbvisionc.

2. This picture leads to ask whether one could speak of cognitive analogs of particle reactions representing interactions of "thought bubbles" i.e. space-time surfaces as correlates of cognition. The incoming and outgoing states would correspond to a Cartesian product of simple subgroups: G=∏^×_i H_i. In this composition the order of factors does not matter and the situation is analogous to a many particle system without interactions. The non-commutativity in general case leads to ask whether quantum groups might provide a natural description of the situation.
