Title: Lattice Defects Described by Difference Discrete Geometry
Abstract:
Deformations of continua have long been formulated through dif erential geometry,
where dislocations are characterized by curvature and torsion. In
parallel, differe-
nce discrete geometry on lattices has been developed as a discrete
counterpart of
differential geometry. In this talk, we discuss an approach to representing one-dim-
ensional lattice defects, namely dislocations, within the framework
of difference
discrete geometry.

Title: Research progress for 2025 and Proposal for future research
plan
Abstract:
First we explain the research progress for 2025 in ``Division of Joint
Research of
Geometry and Natural Science''. In more detail, we recall the original
research plan
and state the overview of research process of the following three
researches:
I. Effect of the local geometric structure of RNA to A-to-I editing;
II. The method to control the shape of the grain boundary;
III. The construction of the geometric model of the quantum walks
on
the graphs equipped with weight and color.
Next we propose the future research plan for each research thema in this
division of research.
