Abstract

In this paper, a sequence of equilibrium problems in metric space is considered. Sufficient conditions for the sequence of approximating problems converging in the sense of Wijsman to the original problem are studied. In addition, concepts of sequentially (generalized) Tykhonov well-posedness under perturbations by a sequence of approximating problems are proposed, then sufficient conditions for such properties are established.
Keywords: Convergence of sets, equilibrium problem, Tykhonov well-posedness, upper semicontinuity, Wijsman convergence

Tóm tắt

Trong bài báo này, dãy các bài toán cân bằng trong không gian metric được xem xét. Các điều kiện đủ cho sự hội tụ theo nghĩa Wijsman của dãy bài toán xấp xỉ về bài toán gốc được quan tâm nghiên cứu. Hơn nữa, các khái niệm về đặt chỉnh Tykhonov (mở rộng) theo dãy dưới dạng nhiễu bởi dãy các bài toán xấp xỉ được đề xuất, tiếp theo đó là việc thiết lập điều kiện đủ cho các dạng đặt chỉnh này.
Từ khóa: Bài toán cân bằng, sự hội tụ Wijsman, sự đặt chỉnh Tykhonov, sự hội tụ của dãy tập, tính nửa liên tục trên
