Convex and Discrete Geometry Summer School

08.28.2023. - 09.01.2023.
Main Lecture Hall, Rényi Institute


Summer School poster

The school offers four mini courses on current hot topics in the field given by Vida Dujmovic (University of Ottawa), Apostolos Giannopoulos (University of Athens), Nabil Mustafa (Université Sorbonne Paris Nord) and Márton Naszódi (Rényi Institute), exercise sessions and a small number of additional talks.The courses and the talks are aimed at graduate students and researchers at the beginning of their career, and should be accessible to a wide audience. Apart from presenting the state of the art, many open problems will be discussed.

Registration is over

Financial Support

We can cover the accommodation, and possibly, the travel expenses for a limited number of participants. You can also stay for a longer period after the Summer School.

Please, indicate on the registration form whether you need such financial support and if you want to stay longer. In case you do, please, do not arrange your travel to Budapest, nor your accommodation, as we may do it for you. Also indicate your desired arrival and departure dates.
