The difference vectors for convex sets and a resolution of the geometry conjecture
Salihah Alwadani, Heinz H. Bauschke, Julian P. Revalski +1
The geometry conjecture, which was posed nearly a quarter of a century ago, states that the fixed point set of the composition of projectors onto nonempty closed convex sets in Hil…
The exact modulus of the generalized concave Kurdyka-Łojasiewicz property
Xianfu Wang, Ziyuan Wang
We introduce a generalized version of the concave Kurdyka-Łojasiewicz (KL) property by employing nonsmooth desingularizing functions. We also present the exact modulus of the gener…
On angles between convex sets in Hilbert spaces
Heinz H. Bauschke, Hui Ouyang, Xianfu Wang
The notion of the angle between two subspaces has a long history, dating back to Friedrichs's work in 1937 and Dixmier's work on the minimal angle in 1949. In 2006, Deutsch and Hun…
Best approximation mappings in Hilbert spaces
Heinz H. Bauschke, Hui Ouyang, Xianfu Wang
The notion of best approximation mapping (BAM) with respect to a closed affine subspace in finite-dimensional space was introduced by Behling, Bello Cruz and Santos to show the lin…
