Transport functions for principal bundles and Morse homology with differential graded coefficients

Maximilian Stegemeyer

We study transport functions as a Morse-theoretical way of describing principal bundles. Transport functions are maps from the spaces of broken gradient flow lines to a topological…

On the string topology of symmetric spaces of higher rank

Philippe Kupper, Maximilian Stegemeyer

The homology of the free and the based loop space of a compact globally symmetric space can be studied through explicit cycles. We use cycles constructed by Bott and Samelson and b…

String topology coproduct and Turaev cobracket on surfaces

Jana Hartenstein, Maximilian Stegemeyer

The string topology coproduct on the homology of the free loop space of a closed manifold induces a string cobracket on -equivariant homology. We give a complete computation o…

Extensions of the loop product and coproduct, the space of antipodal paths and resonances of closed geodesics

Maximilian Stegemeyer

We study the space of paths in a closed manifold with endpoints determined by an involution . If the involution is fixed point free and if is -connected…

String topology on the space of paths with endpoints in a submanifold

Maximilian Stegemeyer

In this article we consider algebraic structures on the homology of the space of paths in a manifold with endpoints in a submanifold. The Pontryagin-Chas-Sullivan product on the ho…

Intersection Multiplicity in Loop Spaces and the String Topology Coproduct

Philippe Kupper, Maximilian Stegemeyer

The string topology coproduct is often perceived as a counterpart in string topology to the Chas-Sullivan product. However, in certain aspects the string topology coproduct is much…
