$h$ -cobordisms between $1$ -connected manifolds with boundary

Ansel Goh

We classify $h$ -cobordisms between compact simply-connected $4$ -manifolds with boundary in both the smooth and topological categories. This extends a result of Kreck, which proved…

Bounds in simple hexagonal lattice and classification of 11-stick knots

Yueheng Bao, Ari Benveniste, Marion Campisi +4

The stick number and the edge length of a knot type in the simple hexagonal lattice (sh-lattice) are the minimal numbers of sticks and edges required, respectively, to construct a…
