Accelerating operator Sinkhorn iteration with overrelaxation
Tasuku Soma, André Uschmajew
We propose accelerated versions of the operator Sinkhorn iteration for operator scaling using successive overrelaxation. We analyze the local convergence rates of these accelerated…

Algorithmic aspects of semistability of quiver representations
Yuni Iwamasa, Taihei Oki, Tasuku Soma
We study the semistability of quiver representations from an algorithmic perspective. We present efficient algorithms for several fundamental computational problems on the semistab…
