Involutlon Fixing The Disjoint Union of Infinite Different Dimensional Real Projective Spaces

光滑流形对合的协边类是拓扑学中的一个重要的问题 。

The bordism of the smooth manifold is very important in topology. This paper discusses the involution fixing the disjoint union of infinite 1 dimensional real projective spaces and two 2 dimensional real projective spaces.
