Quantum fractional revival on unitary Cayley graphs over finite commutative rings
Saowalak Jitngam, Poom Kumam, Songpon Sriwongsa
In this paper, we investigate the existence of quantum fractional revival in unitary Cayley graphs over finite commutative rings with identity. We characterize all finite local rin…
A self-adaptive subgradient extragradient method with conjugate gradient-type direction for pseudomonotone variational inequalities
Ibrahim Arzuka, Parin Chaipunya, Poom Kumam
This paper introduces a subgradient extragradient algorithm with a conjugate gradient-type direction to solve pseudomonotone variational inequality problems in Hilbert spaces. The…
A product of strongly quasi-nonexpansive mappings in Hadamard spaces
Wiparat Worapitpong, Parin Chaipunya, Poom Kumam +1
In this paper, we prove that the product of strongly quasi-nonexpansive -demiclosed mappings is also a strongly quasi-nonexpansive orbital -demiclosed mapping in Hadamard s…
Variational principles using a non-symmetric non-triangular distance
Natthaya Boonyam, Parin Chaipunya, Poom Kumam
We consider Borwein-Preiss and Ekeland variational principles using distance functions that neither is symmetric nor enjoy the triangular inequality. All the given results rely exc…
An existence theorem for single leader multi-follower games with direct preference maps
Yutthakan Chummongkhon, Poom Kumam, Parin Chaipunya
This paper concerns with an existence of a solution for a single leader multi-follower game (SLMFG), where the followers jointly solve an abstract economy problem. Recall that an a…
