ENTR Seminar
Early Number Theory Researchers Seminar


Unfortunately, most, if not all, recent in person seminars and summer schools have been cancelled due to the ongoing pandemic. Usually, these events present an excellent opportunity for young researchers to enter the community and to build research connections through associated social gatherings. A function that has barely been covered by the formats of their online alternatives.

This seminar, addressed to young researchers specifically, is meant as an option to make up for the lost opportunities and get to know other young researchers in the field of number theory. Participants are strongly encouraged to give a talk.
