SEMINARS, GAUGE-TOPOLOGY-SYMPLECTIC
November 17, 2023 3:30 pmng-Mills gauge theory with gauge group SU(2) has played a significant role in the study of the topology of 3- and 4-manifolds. It is natural to ask whether we obtain...

SEMINARS, OPEN NEIGHBORHOOD
November 15, 2023 4:30 pmThe subject of knot theory concerns the phenomena of "knotting", "tangling", and "braiding", investigated from a mathematical point of view. I'll discuss a family of tangles called rational tangles and...
