Let \(p\) be a fixed prime number. Let \(G\) denote a finite \(p\)-perfect group. This book looks at the homotopy type of the \(p\)-completed classifying space \(BG_p\), where \(G\) is a finite \(p\)-perfect group. The author constructs an algebraic analog of the Quillen's "plus" construction for differential graded coalgebras. This construction is used to show that given a finite \(p\)-perfect group \(G\), the loop spaces \(BG_p\) admits integral homology exponents. Levi gives examples to show that in some cases our bound is best possible. It is shown that in general \(B\ast _p\) admits infinitely many non-trivial \(k\)-invariants. The author presents examples where homotopy exponents exist. Classical constructions in stable homotopy theory are used to show that the stable homotopy groups of these loop spaces also have exponents.


Researchers in algebraic topology, and finite group theory and homotopy theory.
