Towards First Quantisation Formalism for AKSZ Theories
Leon Menger, Pavel Mnev
\noindent Given an AKSZ theory on a manifold , with target a graded vector space , we formulate a 1-dimensional theory on graphs (the ``first quanti…

Effect of Torsion on Neutron Star Structure in Einstein-Cartan Gravity
Cédric Jockel, Leon Menger
Einstein-Cartan gravity is a close historical sibling of general relativity that allows for spacetime torsion. As a result, angular momentum couples to spacetime geometry in a simi…

Gravity with torsion as deformed theory
Alberto S. Cattaneo, Leon Menger, Michele Schiavina
We study a family of (possibly non topological) deformations of theory for the Lie algebra obtained by quadratic extension of by an orthogonal module. The…
