Поредната сбирка на СЕМИНАРА на секция "Математическо моделиране и числен анализ" ще се състои на  30.01.2025 г. (четвъртък) от 14:00 часа по Zoom. Доклад на тема: Some mathematical aspects of simulation modeling of physiological processes in plants ще изнесе Dr. Alex Topaj (Bureau Hyperborea Ltd). Резюме: The contribution presents the author's experience of using mathematical methods to describe plant physiology processes in applied crop models. In contrast to the simplified data-based empirical approach, the mechanistic description of plant vital processes in theory allows us to obtain new knowledge and to develop the universal crop models with parameters having physical meaning. Such explanatory models, in addition to the traditional cause-and-effect method (the flow-balance approach, leading to systems of differential or difference equations), can also successfully apply [...]

Поредната сбирка на СЕМИНАРА на секция "Математическо моделиране и числен анализ" ще се състои на  23.04.2025 г. (сряда) от 14:00 часа в зала 478 на ИМИ - БАН. Доклад на тема: Multiscale Leading Edge and Bulk Dynamics for Tumour Invasion in Fibrous Environment ще изнесе Dr. Dumitru Trucu (University of Dundee, Шотландия). Резюме: Despite all recent in vivo, in vitro, and in silico advances, the understanding of the genuine biologically multiscale process of solid tumour invasion remains one of the greatest open questions for scientific community. In this talk we present novel mathematical multiscale moving boundary modelling and structural analytical approaches for tumour invasion. Specifically, we focus on characterising mathematically key aspects of the dynamic interactions that the migratory cancer cells population and the accompanying matrix [...]

Поредната сбирка на семинара на секция Математическо моделиране и числен анализ ще се състои на 24.11.2025 г., понеделник, от 14:00 часа в зала 503 на Института по математика и информатика. Доклад на тема   Modelling financial crisis propagation as an epidemic on multiplex networks ще изнесе д-р Малвина Божидарова (Russell Group Limited) Резюме: We propose a novel framework for modelling the spread of financial crises in complex networks, combining financial data, Extreme Value Theory and an epidemiological transmission model. We accommodate two key aspects of contagion modelling: fundamentals-based contagion, where the transmission is due to direct financial linkages, and pure contagion, where a crisis might trigger additional crises due to global effects. We use stock price, geographical location and economic sector data for a [...]
