SUMMARY:Общ семинар на секция "Анализ\, геометрия и топология" и МЦМН
DESCRIPTION:На 15 юли 2025 г. от 13:00 часа в зала 403 на ИМИ-БАН ще се проведе съвместно заседание на Общия семинар на секция “Анализ\, геометрия и топология” и Международния център по математически науки (ICMS-Sofia). \nДоклад на тема: \nWeak Metric Structures on Generalized Riemannian Manifolds\nще изнесе Milan Zlatanovic\, University of Niš\, Serbia. \nРезюме. Linear connections with torsion are important in the study of generalized Riemannian manifolds (\(M\)\, \(G=g+F\))\, where the symmetric part \(g\) of \(G\) is a non-degenerate (0\,2)-tensor and \(F\) is the skew-symmetric part. Some space-time models in theoretical physics are based on \((M\, G=g+F)\)\, where \(F\) is defined using a complex structure. In the lecture\, we will show more general models\, where \(F\) has constant rank and is based on weak metric structures (introduced by the V. Rovenski and R. Wolak)\, which generalize almost contact and \(f\)-contact structures. We consider metric connections (i.e.\, preserving \(G\)) with totally skew-symmetric torsion tensor. For \(\mbox{rank}(F)= \mbox{dim} M\) and non-conformal tensor \(A^2\)\, where \(A\) is a skew-symmetric (1\,1)-tensor adjoint to \(F\)\, we apply weak almost Hermitian structures to fundamental results (by S. Ivanov and M. Zlatanovic) on generalized Riemannian manifolds and prove that the manifold is a weighted product of several nearly Kahler manifolds corresponding to eigen-distributions of \(A^2\). For \(\mbox{rank}(F)< \mbox{dim} M\) we apply weak \(f\)-structures and obtain splitting results for generalized Riemannian manifolds.\n(This is joint work with Vladimir Rovenski\, Department of Mathematics\, University of Haifa). \nПосещението на лектора е финансирано по Научна програма “Повишаване на изследователския капацитет в областта на математическите науки (ПИКОМ)”\, № ДО1-67/05.05.2022. \n\n
