Abstract

Professor Paul Szeptycki, a renowned set theorist and set-theoretical topologist working at the York University (Canada), will visit the University of São Paulo for 15 days. We will intensively work to obtain new results in problems of interest. During this visit I will start working in new lines of research, which will lead to further projects in the near future. Professor Szeptycki will also give a talk and work with other people in the state, such as Vinicius Rodrigues, a postdoctoral researcher at the University of São Paulo who was his former postdoc. (AU)
