Title: Jones Isomorphism Theorem
Abstract: Then we will outline a proof of Jones Isomorphism Theorem using
simplicial sets and hence obtain the homology of the loop space of spheres.

Title: Coding theory and algebraic properties of matroids
Abstract:
We will show how one can determine properties of linear codes, by
studying algebraic properties of matroids,
which in a natural way are associated to the codes. Concretely, one studies
resolutions of Stanley-Reisner rings associated
to the simplicial independence complexes of the matroids involved. From
these resolutions one may extract generalized Hamming weights and higher
weight spectra, of the codes in question.
