Some numerical characteristic inequalities of compact Riemannian manifolds
Sergey Stepanov, Irina Tsyganok
In this paper, we consider numerical characteristics of the connected compact Riemannian manifold (M, g) such as the supremum and infimum of the scalar curvature s, Ricci curvature…

Prediction of discretization of online GMsFEM using deep learning for Richards equation
Denis Spiridonov, Sergei Stepanov, Tina Mai
We develop a new coarse-scale approximation strategy for the nonlinear single-continuum Richards equation as an unsaturated flow over heterogeneous non-periodic media, using the on…

Back to almost Ricci solitons
Vladimir Rovenski, Sergey Stepanov, Irina Tsyganok
In the paper, we study complete almost Ricci solitons using the concepts and methods of geometric dynamics and geometric analysis. In particular, we characterize Einstein manifolds…
