SUMMARY:Семинар "Алгебра и логика"
DESCRIPTION:На 9 юли 2021 г. (петък) от 13:00 часа ще се проведе дистанционно заседание на семинара по „Алгебра и логика”. \nДоклад на тема \nThe mysterious Kronecker coefficients of the Symmetric group\nще изнесе Greta Panova (University of Southern California\, USA). \nАбстракт. Algebraic Combinatorics is a field of mathematics which studies discrete objects often originating in Representation Theory\, Algebra\, Algebraic Geometry\, Number Theory via combinatorial methods. One of its oldest problems concerns the Kronecker coefficients of the Symmetric Group. They are originally defined by Murnaghan more than 80 years ago as the multiplicities of the irreducible modules in the factorization of the tensor product of two other irreducible modules. They actually generalize the Littlewood-Richardson coefficients in the analogous problem for the general linear group. Despite their algebraic nature as nonnegative integers\, no combinatorial formula or interpretation is known. Kronecker coefficients have recently played a role in Computational Complexity Theory both as a problem and as a solution. \nIn this talk I will give a brief overview of the developments over the past 10 years. I will show how despite our very limited knowledge we can still use the Kronecker coefficients to solve other\, seemingly unrelated problems\, related to enumeration of integer partitions (Sylvester’s unimodality theorem). I will also discuss some of their computational complexity aspects. \n\nСеминарът ще се проведе посредством платформата Zoom и всеки желаещ може да се присъедини като последва линка: \nhttps://us02web.zoom.us/j/85137375021?pwd=RE5QczdFTE1xL1R6MnI2b1lkcGczQT09 \nTopic: Онлайн семинар на секция “Алгебра и логика”\nTime: July 09\, 2021 13:00 PM Sofia\nMeeting ID: 851 3737 5021\nPasscode: 035647 \n\nОт секция „Алгебра и логика” на ИМИ – БАН\nhttp://www.math.bas.bg/algebra/seminarAiL/ \n===================================================
