Finite convergence of locally proper circumcentered methods
Hui Ouyang
In view of the great performance of circumcentered isometry methods for solving the best approximation problem, in this work we further investigate the locally proper circumcenter…
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…
Projecting onto intersections of halfspaces and hyperplanes
Hui Ouyang
It is well-known that the sequence of iterations of the composition of projections onto closed affine subspaces converges linearly to the projection onto the intersection of the af…
