ABSTRACT

In this paper, we introduced and studied some basic properties of weaker form of multifunction such as upper and lower 􀝉􀯪􀯚-continuous multifunction. We obtain some of its characterizations with totally 􀝉􀯪􀯚- closed graph and strongly 􀝉􀯪􀯚- closed graph in Minimal Structures. AMS Subject Classification: 54C08, 54C60.

Keywords :Strongly 􀝉􀯪􀯚- closed graph, totally 􀝉􀯪􀯚- closed graph, 􀝉􀯪􀯚- compact, 􀝉􀯪􀯚- connected and etc.
