Abstract:
It is shown that if $r:X \to Y$ is a refinable map between compacta and $Y$ is calm, then $r$ is a shape equivalence. As a corollary, if $r:X \to Y$ is a refinable map between compacta and either $X$ or $Y$ is ${S^n}$-like $(n \geqslant 1)$, then $r$ is a shape equivalence, where ${S^n}$ denotes the $n$-sphere.References
