Homotopical Intersection Theory, I
John R. Klein, E. Bruce Williams
We give a new approach to intersection theory. Our "cycles" are closed manifolds mapping into compact manifolds and our "intersections" are elements of a homotopy group of a certai…
The homotopy invariance of the string topology loop product and string bracket
Ralph L. Cohen, John Klein, Dennis Sullivan
Let M be a closed, oriented, n -manifold, and LM its free loop space. Chas and Sullivan defined a commutative algebra structure in the homology of LM, and a Lie algebra structure i…
Outer authomorphisms and the Jacobian
Kiyoshi Igusa, John Klein, E. Bruce Williams
A graphs of rank n (homotopy equivalent to a wedge of n circles) without ``separating edges'' has a canonical n-dimensional compact C^1 manifold thickening. This implies that the c…
On C.T.C. Wall's suspension theorem
Mokhtar Aouina, John R. Klein
Almost forty years ago, C.T.C. Wall systematically analyzed the set of "thickenings" of a finite CW complex. Of the results he obtained, probably the most computationally important…
