Abstract

In this paper, we consider the strong equilibrium problems involving Lorentz cone in metric space. Sufficient conditions for upper semicontinuity and closedness of the solution maps of these problems are established. We provide numerous examples to show that all the imposed assumptions are essential. As applications of the main results, the stability of solutions for the vector variational inequality problems involving Lorentz cone in metric space are derived.
Keywords: Lorentz cone, upper semicontinuity, closedness, equilibrium problem, variational inequality

Tóm tắt

Trong bài báo này, chúng tôi xét các bài toán cân bằng mạnh theo nón Lorentz trong không gian mêtric. Các điều kiện đủ cho tính nửa liên tục trên, tính đóng của ánh xạ nghiệm cho bài toán đang xét cũng được thiết lập. Chúng tôi đưa ra nhiều thí dụ để chỉ ra rằng tất cả các giả thiết đưa ra là tính cốt yếu. Ứng dụng các kết quả đạt được vào bài toán bất đẳng thức biến phân theo nón Lorentz cũng được thảo luận.
Từ khóa: Nón Lorentz, tính nửa liên tục trên, tính đóng, bài toán cân bằng, bài toán bất đẳng thức biến phân
