SL2 tropicalizations through valuation algebra, Geometry seminar talk by Andrei Bengus-Lasnier

2025-11-24T15:25:29+02:00November 24th, 2025|Geometry Seminar|

In this talk I will introduce valuation-theoretic tools, such as the graded algebra grν(R) of a general valuation ν on a commutative ring R. This will serve as a tool to algebraically encode the leading terms of our analytic solutions. The graded algebra construction presents certain advantages, such as functoriality, which is essential for proving the following lifting theorem.

Tropical curves with applications, Geometry seminar talk by Petar Petrov

2025-11-07T11:21:37+02:00November 7th, 2025|Geometry Seminar|

This is an introduction to tropical geometry in two talks, mainly in case of curves. The stress will be put on the applications in complex and real algebraic geometry. At the end a few other approaches will be discussed briefly.

IMI-BAS Launches the Atanasoff Memorial Lecture Series Celebrating John Vincent Atanasoff

2025-11-06T17:19:49+02:00November 6th, 2025|News|

On November 10, 2025, the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences will host the Atanasoff Memorial Day event - a new initiative of the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences and the International Center for Mathematical Sciences (ICMS-Sofia) at the IMI-BAS. The organizers' ambition is to hold the Atanasoff Memorial Lecture Series program every year, thus commemorating the memory of John Vincent Atanasoff (1903–1995) - a computer pioneer, inventor of a model of an electronic digital computer and renowned as the "Bulgarian father of the electronic computer". It aims to celebrate the intersection of mathematics, computation, and the sciences of complexity — the very domains that unite topology, geometry, and machine learning in the 21st century.
