TGD leads to several proposals for the exact solution of field equations defining space-time
surfaces as preferred extremals of twistor lift of Kahler action. So called M 8-H duality is one …

The existence of exotic smooth structures even in the simplest possible 4-D space R4 might
have some relevance for TGD. The study of the smooth structures in 4-D case involves …

Exotic smooth structures appearing only in dimension D= 4 are problematic from the point of
view of general relativity since they are accompanied by time loops and thus by causal …

Holography= holomorphy vision generalizes the realization of quantum criticality in terms of
conformal invariance. Holography= holomorphy vision provides a general explicit solution to …

What gravitons are in the TGD framework? This question has teased me for decades. It is
easy to understand gravitation at the classical level in the TGD framework but the …
