Abstract:
Borsuk asked in 1933 if every set of diameter one in Euclidean d-space can
be covered by d + 1 sets of smaller diameter. In 1993, a negative solution,
based on a theorem by Frankl and Wilson, was given by Kahn and the
speaker. In the lecture I will present various questions and results related
to Borsuk’s covering problem.
