A scientific workshop “Numerical and Symbolic Scientific Computing” was held in Sofia On 20-23 September, within the Year of Bulgaria at JINR, a scientific workshop “Numerical and Symbolic Scientific Computing” was held in Sofia (Bulgaria) in a hybrid format. The primary objective of the workshop is the exchange of knowledge and the formation of new collaborations between JINR’s and Bulgarian scientists working in the field of numerical methods, symbolic computations, scalable algorithms and their parallel implementations for solving mathematical physics problems. 30 specialists from MLIT, Bulgaria, Slovakia and the Czech Republic took part in the workshop. There were given reports on topics such as the analytical modeling and numerical solution of systems of equations that describe telecommunication systems; the mathematical modeling of biological structures by molecular dynamics methods; the application of neural networks in biology tasks, the numerical modeling of processes and phase transitions of neutron stars; the application of scalable algorithms and their parallel implementations for solving mathematical physics problems. A special memorial session was dedicated to the 95th anniversary of the birth of Evgeny Petrovich Zhidkov, a famous mathematician, an outstanding specialist in applied mathematics, mathematical modeling and numerical methods for solving physics problems. Fruitful discussions of the presented talks were held during the workshop. In conclusion the organizers expressed their intention and hope for conducting the workshop on a regular basis. More...
