Branching stochastic processes as models of Covid-19 epidemic development
Nikolay M. Yanev, Vessela K. Stoimenova, Dimitar V. Atanasov
The aim of the paper is to describe two models of Covid-19 infection dynamics. For this purpose a special class of branching processes with two types of individuals is considered.…

The aim of the paper is to describe a model of the development of the Covid-19 contamination of the population of a country or a region. For this purpose a special branching proces…
Long-term variations in the correlation between NAO and solar activity: the importance of North-South solar activity asymmetry for atmospheric circulation
Katya Georgieva, Boian Kirov, Peter Tonev +2
General atmospheric circulation is the system of atmospheric motions over the Earth on the scale of the whole globe. Two main types of circulation have been identified: zonal - cha…
