Title: Phases of N=2 theories in 1+1 dimensions with boundary
Abstract: This is an introduction to my recent paper (with Manfred Herbst and David Page) of 265 pages. We find a simple and transparent description of D-branes over a large region of the moduli space which includes geometric as well as non-geometric regimes. I believe that this will eventually provide useful tools in construction of models of particle physics and cosmology. This work also has mathematical aspects, and is in fact motivated by recent development in homological algebra. Our work provides a unified picture to "equivalences of categories" that had been found during the last decade.
