Anssi Lahtinen
I am a postdoc at the KTH Royal Institute of Technology.
Before coming to KTH, I used to be a postdoc at the
University of Copenhagen
Department of Mathematical Sciences, where I was
a member of the
topology group
and part of the
Centre for Symmetry and Deformation.
I received my PhD from Stanford University in
2010. My advisor there was Professor
Ralph Cohen.
My research interests lie in algebraic topology and homotopy theory,
in particular string topology, parametrized homotopy theory, and field theories.
Currently I am especially interested in the string topology of classifying
spaces.

Fourth Arolla Conference on Algebraic Topology.

Higher operations in string topology of classifying spaces
In preparation. This paper will contain explicit computations
of higher string topology operations for a number of different
groups and include applications to the homology of
holomorphs and automorphism groups of free groups.
Some information appears on the
slides
for my talk at the Goodwillie birthday conference in Dubrovnik.
