The aim of this paper is to study the relationship among Minty vector variationallike inequality problem, Stampacchia vector variational-like inequality problem and vector optimization problem involving(G, α)-invex functions. Furthermore, we establish equivalence among the solutions of weak formulations of Minty vector variational-like inequality problem,Stampacchia vector variational-like inequality problem and weak efficient solution of vector optimization problem under the assumption of(G, α)-invex functions. Examples are provided to elucidate our results. 相似文献

Let K denote a locally compact commutative hypergroup, L
1(K) the hypergroup algebra, and α a real-valued hermitian character of K. We show that K is α-amenable if and only if L
1(K) is α-left amenable. We also consider the α-amenability of hypergroup joins and polynomial hypergroups in several variables as well as a single variable. 相似文献

For α∈N with α≥2, we define and characterize α-inflatable semigroups,S and establish that the product (βS/S,·)·(βS/S,·) of Stone-Ĉech remainders does not contain the closure of the minimal ideal of (βS,·), the Stone-Ĉech compactification ofS. From this result, one can easily derive Ruppert's result that the minimal ideal of a compact left-topological semigroup
is not necessarily closed.

A generalization of the concept of a flock of a quadratic cone in PG(3,q), q even, where the base of the cone is replaced by a translation oval, was introduced in [4] and is the focus of this work. The related idea of a q-clan is also generalized and studied with a particular emphasis on the connections with hyperovals. Several examples are given leading to new proofs of the existence of known hyperovals, unifying much of what has been done in this area. Finally, a proof that the Cherowitzo hyperovals do form an infinite family is also included. 相似文献
