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 spa…
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…
