“…Let u i generate H i n .X I Z/, for i D 0; 1; 2 and 3. Then the structure of the Z-cohomology ring of X is determined by the two integers a and b for which u 2 1 D au 2 and u 1 u 2 D bu 3 . In this case, X is said to be of type .a; b/.…”
Let X be a space of type .a; b/ equipped with a free G-action, with G D Z 2 or S 1. In this paper, we prove some theorems of Borsuk-Ulam-type and the corresponding parametrized versions for such G-spaces. 55M20; 55R91, 55R25

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
