Topological Twisting of 4d Supersymmetric Field Theories
Gregory W. Moore, Vivek Saxena, Ranveer Kumar Singh
We discuss what topological data must be provided to define topologically twisted partition functions of four-dimensional supersymmetric field theories. The origina…

A T-Duality of Non-Supersymmetric Heterotic Strings and an implication for Topological Modular Forms
Vivek Saxena
Motivated by recent developments connecting non-supersymmetric heterotic string theory to the theory of Topological Modular Forms (TMF), we show that the worldsheet theory with cen…
