Seminars

The EFNet #math seminar takes place in the #mathematics channel on EFNet. The "talks" are expository in nature and on topics that are usually accessible to a wide audience. #mathematics maybe be moderated while a seminar is in progress. If you have a question (given the channel is not +m), please say "!" and patiently wait for lecturer's attention.
