n-Shape equivalence and triads
Takahisa Miyata
Sažetak
This paper concerns the shape theory for triads of spaces which was intoduced by the author. More precisely, in the forst part, the shape dimension for triads of spaces (X; X0, X1) is introduced, and its upper and lower bounds are given in terms of the shape dimension of X0, X1, X0 ∩ X1 and X. In the second part, a Whitehead type theorem for triad of spaces and a Mayer-Vietoris type theorem concerning n-shape equivalence are obtained.
