studies on the topologic deffects that occur changing the continuous space-time
through of spontaneous breaking of symmetries,and permiting space-time sheet many.then have a geometrydynamics topologic that does connect the quantic mechanical wavefunctions and general relativity theory that are emmerged superstring theories.
the topologic change is a fascinanting theme to physics to understand the several
topologic manifolds that are linked to some physical conceits,as mirror symmetry
and its breakdown
