## Abstract

In the TGD Universe space-time surfaces within causal diamonds (CDs) are fundamental

objects.

1. M8 − H duality means that one can interpret the space-time surfaces in two manners:

either as an algebraic surface in complexified M8

or as minimal surfaces in H = M4×CP2.

M8 − H duality maps these surfaces to each other.

2. Minimal surface property holds true outside the frame spanning minimal surface as 4-D

soap film and since also extremal of K¨ahler action is in question, the surface is analog

of complex surface. The frame is fixed at the boundaries of the CD and dynamically

generated in its interior. At frame the isometry currents of volume term and K¨ahler

action have infinite divergences which however cancel so that conservation laws coded

by field equations are true. The frames serve as seats of non-determinism.

3. At the level of M8

the frames correspond to singularities of the space-time surface. The

quaternionic normal space is not unique at the points of a d-dimensional singularity and

their union defines a surface of CP2 of dimension dc = 4 − D < d defining in H a blow

up of dimension dc.

In this article, the inspiration provided by 2-D minimal surfaces is used to deepen the TGD

view about space-time as a minimal surface and also about M8 − H duality and TGD itself.

1. The properties of 2-D minimal surfaces encourage the inclusion of the phase with a

vanishing cosmological constant Λ phase. This forces the extension of the category of

real polynomials determining the space-time surface at the level of M8

to that of real

analytic functions. The interpretation in the framework of consciousness theory would

be as a kind of mathematical enlightenment, transcendence also in the mathematical

sense.

2. Λ > 0 phases associated with real polynomials as approximations of real analytic functions

would correspond to a hierarchy of inclusions of hyperfinite-factors of type II1

realized as physical systems and giving rise to finite cognition based on finite-D extensions

of rationals and corresponding extensions of p-adic number fields.

3. The construction of 2-D periodic minimal surfaces inspires a construction of minimal

surfaces with a temporal periodicity. For Λ > 0 this happens by gluing copies of minimal

surface and its mirror image together and for Λ = 0 by using a periodic frame.

A more general engineering construction using different basic pieces fitting together like

legos gives rise to a model of logical thinking with thoughts as legos. This also allows

an improved understanding of how M8 − H duality manages to be consistent with the

Uncertainty Principle (UP).

4. At the physical level, one gains a deeper understanding of the space-time correlates

of particle massivation and of the TGD counterparts of twistor diagrams. Twistor lift

predicts M4 K¨ahler action and its Chern-Simons implying CP breaking. This part is

necessary in order to have particles with non-vanishing momentum in the Λ = 0 phase.
