Key words and phrases: approximation of mapping; differential inclusions; disturbed inclusions; functional inclusions; multi-valued mapping.
Abstract: The paper deals with inclusion, the right part of which consists of the algebraic sum of values of “good” (having closed images) and “bad” (without property of closeness and convexity of values) of multi-valued mappings. Such inclusions are called disturbed. The first part of the paper formulates basic theories of such inclusions and proves that collection of solutions for such inclusions can lose the property of stability (“insignificant” changes of the first part can lead to significant changes in the collection of solutions). The necessary and sufficient condition to provide the property of stability of the solutions collection is formulated.
