A Geometric Reverse To The Plus Construction And Some Examples Of Pseudo-Collars On High-Dimensional Manifolds
Jeffrey Rolland
In this paper, we develop a geometric procedure for producing a reverse to Quillen's plus construction, a construction called a 1-sided h-cobordism or semi-h-cobordism. We then use…

Some Results on Pseudo-Collar Structures on High-Dimensional Manifolds
Jeffrey Rolland
In this paper, we recall Quillen's plus construction for high-dimensional smooth manifolds and the solution to the group extension problem. We then develop a geometric procedure du…
