Given a circle-valued Morse function of a closed oriented manifold, we prove that Reidemeister torsion over a non-commutative formal Laurent polynomial ring equals the product of a certain ...

We recall some of the obstacles which arise when one tries to reconcile the general theory of relativity with quantum theory. We consider the possibility that gravitation theories which include ...

They've used their carefully calibrated torsion balances to disprove a hypothetical force, feel the pull of dark matter and hunt the axion wind. When you purchase through links on our site, we may ...

Homotopy theory in algebra is a dynamic field that adapts concepts originally developed in topology to the study of algebraic structures. In particular, the framework of chain complexes and derived ...
