General Notion of Curvature in Catastrophe Theory Terms
Petko Nikolov, Lora Nikolova, Gergana Ruseva
We introduce a new notion of a curvature of a superconnection, different from the one obtained by a purely algebraic analogy with the curvature of a linear connection. The naturaln…

Description of all conformally invariant differential operators, acting on scalar functions
Petko Nikolov, Tihomir Valchev
We give an algorithm to write down all conformally invariant differential operators acting between scalar functions on Minkowski space. All operators of order k are nonlinear and a…

Dimensional Reduction of Dirac Operator
Petko A. Nikolov, Gergana R. Ruseva
We construct an explicit example of dimensional reduction of the free massless Dirac operator with an internal SU(3) symmetry, defined on a twelve-dimensional manifold that is the…
