The Workshop aimed at bringing together physicists and mathematicians working on different aspects of quantum geometry, random surfaces, random matrices and simplicial quantum gravity, for discussion of recent progress. This involves analytical and numerical work, including the "traditional" use of matrix models and dynamical triangulations, as well as the application of matrix model techniques to M(atrix) theory and combinatorial problems.
The workshop was funded by MaPhySto and the grant Global analysis and applications of The Danish Natural Science Research Council.
