An infeasible interior-point arc-search method with Nesterov's restarting strategy for linear programming problems
Einosuke Iida, Makoto Yamashita
An arc-search interior-point method is a type of interior-point methods that approximates the central path by an ellipsoidal arc, and it can often reduce the number of iterations.…
Exact SDP relaxations for quadratic programs with bipartite graph structures
Godai Azuma, Mituhiro Fukuda, Sunyoung Kim +1
For nonconvex quadratically constrained quadratic programs (QCQPs), we first show that, under certain feasibility conditions, the standard semidefinite (SDP) relaxation is exact fo…
Injectivity for algebras and categories with quantum symmetry
Lucas Hataishi, Makoto Yamashita
We establish the existence of injective envelopes for unital Yetter-Drinfeld C*-algebras, and a related class of bimodule categories over rigid C*-tensor categories. This implies m…
Poisson-Lie Group structures on semidirect products
Floris Elzinga, Makoto Yamashita
We look at the Poisson structure on the total space of the dual bundle to the Lie algebroid arising from a matched pair of Lie groups. This dual bundle, with the natural semidirect…
Crossed Product Equivalence of Quantum Automorphism Groups
Michael Brannan, Floris Elzinga, Samuel J. Harris +1
We compare the algebras of the quantum automorphism group of finite-dimensional C-algebra , which includes the quantum permutation group , where . We s…
Lieb type convexity for positive operator monotone decreasing functions
Hans Henrich Neumann, Makoto Yamashita
We prove Lieb type convexity and concavity results for trace functionals associated with positive operator monotone (decreasing) functions and certain monotone concave functions. T…
