Structure of the Projective Group in A Pseudo-Riemannian Space

We study n-dimensional pseudo-Riemannian spaces Vⁿ(g_ij) with an arbitrary signature that admit projective motions, i.e., groups of continuous transformations preserving geodesics. In particular, we find the metric of a pseudo-Riemannian space of special type and establish important projective-group properties of this space.     

Ultrametric Diffusion,Exponential Landscapes,and the First Passage Time Problem

In this article we study certain ultradiffusion equations connected with energy landscapes of exponential type. These equations are connected with the \(p\)-adic models of complex systems introduced by Avetisov et al. We show that the fundamental solutions of these equations are transition density functions of Lévy processes with state space \(\mathbb{Q}_{p}^{n}\), we also study some aspects of these processes including the first passage time problem.     

Note on the Hochschild cohomology of Hopf–Galois extension

We generalize [4, Theorem 4.3] to the case of Hopf–Galois extension, by introducing the cotensor product of a comodule algebra and its opposite algebra, and then give some applications.
