Barbatis Gerassimos

Barbatis Gerassimos is an Adjunct Professor in the Department of Mathematics at the National and Kapodistrian University of Athens. His research focuses on advanced topics in mathematical analysis, partial differential equations, and spectral theory, with a particular emphasis on inequalities such as Hardy, Rellich, and Sobolev. He has contributed to the study of heat kernels, Schrödinger operators, and geometric analysis in non-Euclidean settings like Finsler metrics and Heisenberg groups. His work frequently explores optimal constants in functional inequalities and their applications to elliptic and parabolic equations.

Key themes in his publications include spectral stability, homogenization of elliptic systems, and boundary behavior analysis. His research bridges theoretical mathematics with applications in physics and engineering, particularly in understanding asymptotic properties and geometric influences on operator behavior. Despite extensive contributions, no scientific awards or student advisees are explicitly mentioned in the provided materials.
