A course on “Braids and Knots” by Professor Vladimir Verchinine (University of Montpellier): Distance learning scheme in the 4th module

Braids and Knots

An introductory level special topics course on “Braids and Knots” by Professor Vladimir Verchinine (University of Montpellier) will be offered in the 4th module via distance learning scheme (Prof. Verchinine is currently in Moscow but the unfortunate epidemic situation does not allow to take full advantage of his location).
 
TIME: Mondays 5pm – 8pm
FIRST CLASS: April 6
 
HOW TO ENROLL: please write to the instructor, Vladimir Verchinine vladimir.verchinine–at--umontpellier–dot--fr. If you would like to earn ECTS credits for this course, please inform Svetlana Balaeva sbalaeva–at--hse–dot--ru – it is not guaranteed that the course can be made creditable but it may be considered.
