SUMMARY:Национален семинар по стохастика
DESCRIPTION:Поредната сбирка на \nНационалния семинар по стохастика\nще се проведе на 20 май 2026 г. (вторник) от 14:00 часа в зала 503 на ИМИ – БАН. \nДоклад на тема \nFinite time blowup and existence of global solutions of a semi-linear stochastic partial differential equation with fractional noise\nще изнесе \nEkaterina Todorova Kolkovska (Center for Research in Mathematics Guanajuato\, Mexico). \nAbstract: We consider a stochastic partial differential equation driven by fractional Brownian motion with Hurst parameter H greater or equal to 1/2 on a bounded domain with smooth boundary and Dirichlet boundary conditions. By means of an associated random partial differential equation\, lower and upper bounds for the blowup time of the solution are given. Sufficient conditions for blowup in finite time and for the existence of a global solution are deduced in terms of the parameters of the equation. For the case H = 1/2 (i.e. for Brownian motion) estimates for the probability of blowup in finite time are given in terms of the laws of exponential functionals of Brownian motion. \nПовече информация за доклада можете да намерите на страницата на семинара:\nhttp://www.math.bas.bg/~statlab/NSPS/ \n
