Polina Vytnova is spending an intermittent 5 weeks travelling back and forth to the Institute of Mathematics in the Polish Academy of Sciences (IM PAN), Warsaw. She is a co-organiser of a 5-week long research programme entitled “Simons Semester: Continued Fractions, Fractals, Ergodic theory and Dynamics“, which takes place 27 April to 31 May. The program is funded by the Simons Foundation and the Ministry of Science and Higher Education of Republic of Poland (link to the programme website here). Its focus is on Continued Fractions and it is at the intersection of several branches of mathematics, including, but not limited to, Number theory and Diophantine analysis, holomorphic dynamics, and dimension theory (aka fractals). The programme is attracting 150 participants and consists of a Research School, a Conference (that takes place next week, 18-22 May) and a series of thematic weeks filled with mini-courses by Early Career Researchers (10 in total). The building in the first photo is the Bedlewo Conference Centre (that belongs to IM PAN). This is where the research school is taking place. It is located about 40km from Poznan, near Mosina (the birth place of Lazarius Fuchs, aka Fuchsian groups).  The photo of the IM PAN, that was used for the programme poster, is the second photo.
