On the interaction of massive spinor particles with external electromagnetic and torsion fields [PDF]
, 1998 We explore the Dirac equation in external electromagnetic and torsion fields. Motivated by the previous study of quantum field theory in an external torsion field, we include a nonminimal interaction of the spinor field with torsion.

Analytic torsion and Reidemeister torsion [PDF]
Proceedings of the National Academy of Sciences, 1977 We announce a proof of the conjecture of Ray and Singer that for a compact Riemannian manifold the analytic torsion and Reidemeister torsion are equal. The proof involves studying the heat equation for certain manifolds M, equipped with metrics g u , 0 < u

Ovarian torsion as an unusual presentation of primary bilateral ovarian lymphoma
Indian Journal of Medical and Paediatric Oncology, 2018 Primary ovarian involvement by Burkitt's lymphoma is rare and accounts for 0.5% of nonHodgkin lymphoma and 1.5% of ovarian tumors. We herein describe a very rare case of primary bilateral ovarian lymphoma in a 14-year-old presenting as ovarian torsion.

Physics Letters B, 1979 Abstract Modifying the Yang-Mills field strength and using a recently proposed generalisation of the usual minimal coupling procedure allows a simple but non-trivial type of dynamic torsion to couple to all gauge fields in a consistent manner. This allows, for the first time, a framework in which no spinning particle is required to be exempted from ...

The action for the (propagating) torsion and the limits on the torsion parameters from present experimental data [PDF]
, 1997 Starting from the well established form of the Dirac action coupled to the electromagnetic and torsion field we find that there is some additional softly broken local symmetry associated with torsion.

On torsion in finitely presented groups [PDF]
, 2016 We give a uniform construction that, on input of a recursive presentation $P$ of a group, outputs a recursive presentation of a torsion-free group, isomorphic to $P$ whenever $P$ is itself torsion-free.
