## General Information

Discrete differential geometry is a field in its nascence. Rooted in the integrability of differentiable objects in geometry, the field is of deep mathematical interest, and have gained interest from prominent mathematicians around the world. Furthermore, it is a field that readily bridges the gap between pure mathematics and applications due to its connection to architecture, computer graphics, and crystal structures, to name a few.

We have designed this workshop specifically so that the material will be introductory but mathematically rigorous. Since the field is relatively new, it is often difficult to find well presented introductory texts or lectures on discrete differential geometry. The aim of the workshop is to provide any researcher or student attending the workshop with well-designed lectures on the basics of discrete differential geometry. Furthermore, we have formulated the lectures so that the material will be accessible and (hopefully) interesting to audience of wide mathematical background, from undergraduate students to active researchers. However, we have also prepared a series of lectures that bridges the gap between basic materials and materials that lead directly to independent research, from the viewpoint of both pure mathematics and applications, with special emphasis on its connections to crystal structures.

This is a workshop that intends to not only introduce the subject of discrete differential geometry, but also become a basis for a community of researchers interested in discrete differential geometry. We cordially invite any researcher or student of mathematics and related fields who are interested in discrete differential geometry to attend this workshop.
