Mathematics Colloquium




"Conferinţele Facultăţii de Matematică" este o serie de expuneri adresate unui public larg de matematicieni, cu subiecte din diverse ramuri ale matematicii sau conexe acestora, realizate de personalităţi ale domeniului.


Programul colocviului


Miercuri 19 octombrie 2022, ora 16 (Amfiteatrul I.3)

  • Prof. dr. Liviu ORNEA, Universitatea Bucureşti, Despre geometria varietatilor Hopf.

Abstract: Varietăţile Hopf sunt câturi ale lui Cn-{0} prin acţiunea unei contracţii olomorfe, inversabile cu centrul în 0. Voi descrie structura complexă şi structura metrică ale acestor varietăţi, combinând tehnici de geometrie şi analiză. Expunerea se bazează pe articole în colaborare cu Misha Verbitsky.


Vineri 2 aprilie 2021, ora 16 (online: Zoom Meeting)

  • Prof. dr. Sorin DASCALESCU, Universitatea Bucuresti, On the classification of finite dimensional Hopf algebras.

Abstract: We present some fundamental facts about the structure of Hopf algebras, and discuss the state of the classification of finite dimensional Hopf algebras, with an emphasis on the pointed and semisimple cases.


Vineri 19 februarie 2021, ora 16 (online: Zoom Meeting)

  • Prof. dr. Constantin ZALINESCU, Academia Romana & Universitatea "Alexandru Ioan Cuza", On entropy optimization and Lagrange multipliers.

Abstract: I shall speak about the use of the Lagrange multipliers method for obtaining the optimal solutions of entropy optimization problems.


Vineri 15 ianuarie 2021, ora 18 (online: Zoom Meeting)

  • Prof. dr. Daniel TATARU, University of California, Berkeley, Free boundary problems for a compressible gas.

Abstract: This talk is concerned with the evolution of an inviscid, compressible gas with a vacuum boundary, e.g. a gaseous star.
This is a degenerate hyperbolic free boundary problem of interest to both mathematicians and physicists. The goal will be to describe a new, Eulerian approach for the study of the local well-posedness for this problem. This is joint work with Mihaela Ifrim, and, in part, with Marcelo Disconzi.


Vineri 11 decembrie 2020, ora 15 (online: Zoom Meeting)

  • Prof. dr. Liviu NICOLAESCU, University of Notre Dame, Spectral perestroika.

Abstract: I will describe how to reconstruct the geometry of a Riemann manifold from the knowledge of eigenvalues and eigenfunctions of the scalar Laplacian and then I will explain the probabilistic flavour of this perestroika.


Joi 14 mai 2020, ora 16 (online: Zoom Meeting)

  • Acad. Viorel BARBU, Academia Romana Nonlinear Fokker-Planck equations and trend to equilibrium in statistical mechanics.

Abstract: One surveys a few recent results on well-posedness and longtime behaviour (H-theorem) of solutions to nonlinear Fokker-Planck equations.
