Applied Mathematics Seminar

Institute of Mathematics and Informatics, BAS Akad.G.Bonchev St, bl. 8, 1113, Sofia

NUMERICAL SOLUTION OF MULTIDIMENSIONAL SPECTRAL FRACTIONAL DIFFUSION PROBLEMS: FROM CAFFARELLI TO BURA Authors: Bálint Farkas, Béla Nagy and Szilárd Révész, Alfréd Rényi Institute of Mathematics Date: June 6, 2023 Time: 5:30 pm Place: Room 503 of IMI - BAS Abstract: We introduce a general framework to investigate minimax problems for sum of translates functions F(x,t)=\sum_k K(t-x_j) or F(x,t)=J(t)+\sum_k K(t-x_j), where K is a general concave "kernel function" and J is an "outer field" function, t runs [0,1], and x=(x_1,...,x_n) is a set of nodes which are used to translate the kernel. Our setup is very close to logarithmic potential theory, but fixing n and focusing on a more detailed analysis, we obtain new results even for very classical problems. Extending a method of P. Fenton, we reach considerable [...]

Algebra and Logic Seminar

Zoom

The next meeting of the Algebra and Logic Seminar will be held on June 9, 2023 (Friday) at 1:00 pm (UTC+3) online in Zoom. A talk on: Old and new aspects of the Poincaré-Birkhoff-Witt theorem will be delivered by Vladimir Dotsenko (Institute for Advanced Mathematical Research (IRMA), University of Strasbourg and CNRS, France). Abstract.The Poincaré-Birkhoff-Witt theorem on universal enveloping algebras of Lie algebras is a fundamental result in many areas of mathematics: from differential geometry and representation theory to homological algebra and deformation quantization. I shall give a short overview of that result and some of its proofs that emerged in about 120 years since Poincaré published a paper about it, and outline a new proof which perhaps captures its category-theoretic essence in the best [...]

BIOMATH 2023 – International conference on Mathematical Methods and Models in Biosciences

Pomorie, Bulgaria Ул. “Проф. Стоянов №5, Поморие, Поморие, Bulgaria

Biomath is an international series of conferences devoted to recent research in life sciences based on applications of mathematics as well as mathematics applied to or motivated by biological studies. It is a multidisciplinary meeting forum for researchers who develop and apply mathematical and computational tools to the study of phenomena in the broad fields of biology, ecology, medicine, biophysics, biochemistry, pharmacokinetics, chemoinformatics, biotechnology, bioengineering, environmental science, etc.

16-th International Workshop on Well-Posedness of Optimization Problems and Related Topics

      The workshop is a continuation of a series of meetings with the same title that was initiated in 1987 in Milan, Italy, by a small group of Bulgarian and Italian mathematicians working in the field of Well-Posedness in Optimization and Related Topics. The subsequent editions of the workshop were held in Sofia (1989), Santa Margherita Ligure (1991), Sozopol (1993), Marseille (1995), Sozopol (1997), Gargnano (1999), Warsaw (2001), Marseille (2003), Borovets (2005), Alicante (2007), Levico Termi (2009), Borovets (2011), Borovets (2018) and Borovets (2021), where the scope and the attendance were substantially enlarged. The aim of the series of workshops is to bring together people that are interested in stability of optimization problems in a broad sense. In particular, the organizers want [...]
