On the generalizations of the Kummer–schwarz equation
YD Bozhkov, PR da Conceição - Nonlinear Analysis, 2020 - Elsevier
We carry out complete group classifications of two non-homogeneous generalizations of the
Kummer–Schwarz equation. In particular we prove that the symmetry algebra for one of …

Symmetries of Ricci flows
In the present work, we find the Lie point symmetries of the Ricci flow on an n-dimensional
manifold, and we introduce a method in order to reutilize these symmetries to obtain the Lie …

Conformal Killing vector fields and Rellich type identities on Riemannian manifolds, II
Y Bozhkov, E Mitidieri - Mediterranean journal of mathematics, 2012 - Springer
We propose a general Noetherian approach to Rellich integral identities. Using this method
we obtain a higher order Rellich type identity involving the polyharmonic operator on …
