wildly imbedded set

This paper presents granulation degree of η- embedded sets of one direction assistant sets A_S(X°) and granulation degree of μ Δ γ -embedded sets of two direction assistant sets A_S(X~*) .

提出单向副集AS(X°)的η-嵌入集的粒度、双向副集AS(X )的μΔγ-嵌入集的粒度等概念;提出单向副集AS(X°)的η-嵌入集的粒度特性定理,双向副集AS(X )的μΔγ-嵌入集的粒度特性定理。
