Optimality conditions and duality relations in nonsmooth fractional interval-valued multiobjective optimization
Nguyen Huy Hung, Nguyen Van Tuyen
This paper deals with Pareto solutions of a nonsmooth fractional interval-valued multiobjective optimization. We first introduce four types of Pareto solutions of the considered pr…

On the flatness and the projectivity over Hopf subalgebras of Hopf algebras over discrete valuation rings
Nguyen Dai Duong, Phung Ho Hai, Nguyen Huy Hung
We study the flatness and the projectivity of Hopf algebras, defined over a Dedekind ring, over their Hopf subalgebras. We give a criterion for the faithful flatness and use it to…

The Uniqueness Of Integrals On Hopf Algebras, A categorical approach
Phung Ho Hai, Nguyen Huy Hung
We propose a new method to investigate the dimension of the space of integrals on a Hopf algebra and other properties of -comodules.
