Abstract

The research focus on properties of zero inflated distributions (binominal, Poisson, negative binominal, etc.) and implement them to certain sets of important combinatorial structures, In fact, we undertake in our study mappings of a finite set into itself, allocations of particles into cells and cells and labeled trees. During the visit to IME-USP, Prof. Mutafchiev will work with Prof. Kolev (MAE), Prof. Y. Kohayakawa (MAP) and their students. (AU)
