SUMMARY:Семинар по Приложна математика
DESCRIPTION:Subdiffusion-reaction systems: from microscopic random walk to the mesoscopic fractional PDE’s\nДокладчик: проф. Сергей Федотов\, ръководител на групата по приложна математика в университета на Манчестър\nДата: 11.09.2024 г.\nЧас: 14:00 ч.\nМясто: зала 403 \nРезюме: An interesting feature of subdiffusion-reaction systems is the lack of a universal model for reactions in subdiffusive media. Consequently\, the coarse-grained fractional subdiffusion-reaction equations depend on the specific details of the underlying microscopic random walk models. This complexity arises from the memory effects inherent in subdiffusive transport systems. Simply adding a reaction term to the transport equation can be physically inconsistent. Due to the memory effect\, the subdiffusion process depends on the entire history of the system’s evolution making the diffusion and reaction processes inseparable. \n

SUMMARY:Семинар "Диференциални уравнения и математическа физика"
DESCRIPTION:На 11.09.2024 г. от 14:00 ч. в зала 478 на ИМИ\nи онлайн в Zoom ще се състои поредната сбирка на\nсеминара по Диференциални уравнения и математическа физика.\nДоклад на тема \nWigner’s elementary systems in de Sitter spacetime\nще изнесе Хамед Педжан. \nАбстракт. Quantum elementary systems are associated with (projective) unitary irreducible representations (UIRs) of the relativity group (or one of its covering groups). This foundational perspective was first introduced by Wigner in his seminal 1939 paper\, within the framework of Einstein-Poincaré relativity. In this talk\, building on Wigner’s approach\, we will briefly introduce the de Sitter relativity group\, its representations\, and outline the basics of constructing elementary systems within the global structure of de Sitter spacetime. \nЛинка към Зуум стаята: \nJoin Zoom Meeting\nhttps://us02web.zoom.us/j/84236008764?pwd=hWm1knPWJteBkh4iMX0mUCVmPIvWMh.1 \nMeeting ID: 842 3600 8764\nPasscode: 349193
