This book presents a selection of papers based on the XXXIII Bia owie a Workshop on Geometric Methods in Physics, 2014. The Bia owie a Workshops are among the most important meetings in the field and attract researchers from both mathematics and physics. The articles gathered here are mathematically rigorous and have important physical implications, addressing the application of geometry in classical and quantum physics. Despite their long tradition, the workshops remain at the cutting edge of ongoing research. For the last several years, each Bia owie a Workshop has been followed by a School...
