SUMMARY:Съвместен семинар на секции ММЧА и МОИ
DESCRIPTION:На 05.01.2023 г. (четвъртък)\, 15:00 в зала 403 на ИМИ \nще се състои съвместен семинар на секциите \nМатематическо моделиране и числен анализ\nи \nМатематически основи на информатиката.\nДоклад на тема \n Universal extrema of potentials of certain classes of spherical designs\nще изнесе проф. Сергей Бородачьов\, Towson University. \nAbstract: We will discuss known results and our work on locations of absolute minima and maxima of the total potential of N points located on a higher-dimensional sphere that form a spherical design of the highest (in some sense) strength. The potential is a completely monotone function of the Euclidean distance squared. These results apply to a quite extensive list of particular spherical configurations. For power-law potentials and vertices of a regular polygon\, regular simplex\, cube\, and cross-polytope\, this problem was earlier solved in the papers by Stolarsky\, Nikolov\, and Rafailov.
