    "Discrete geometric analysis" is a mathematical framework, which enables us to describe and analyze the correlation between microscopic structures and macroscopic properties of various materials. In this project, we supported the development of such a framework to solve the "forward problems" predicting materials properties from their structure and the "inverse problems" suggesting reasonable structures from desired properties. Especially, we introduced various approaches to promote the spontaneous interaction among "mathematics", "materials science" and "data science", and successfully contributed to proposing a novel strategy for design of the next generation materials.

    A novel crystal structure represented by a carbon structure was analyzed using discrete geometry analysis.
    In order to analyze the crystal structure, which is a typical example of the carbon structure from the viewpoint of discrete geometry analysis, Define a trivalent discrete surface, define its Gaussian curvature and mean curvature, It shows the negative curvature of the structure that was conventionally called ``negative curvature carbon structure'', etc. It was shown that the structure that appears in material science can be described by the method of discrete geometry analysis. In addition, by improving the energy of the graph, we proposed a high-speed calculation method for the curved graphene structure.
    An example is shown in which there is a strong correlation between the curvature of a curved surface and its physical properties.

    In this research, I treated several topics in mathematical crystallography. Especially motivated by the recent development in systematic design of crystal structures, I discussed interesting relationships among seemingly irrelevant subjects; say, standard crystal models, tight frames in the Euclidean space, rational points on Grassmannian, and quadratic Diophantine equations. The central object in this study is what I call crystallographic tight frames, which are considered a generalization of root systems. I also made a remark on the connections with tropical geometry, a relatively new area in mathematics, specifically with combinatorial analogues of the Abel-Jacobi map and Abel's theorem.
    What is more, I explained how the idea of Riemann sum is linked to other branches of mathematics; for instance, some counting problems in elementary number theory and the theory of quasicrystals, the former having a long history and the latter being an active field still in a state of flux.

    We call a trivalent graph in the 3-dimensional Euclidean space a discrete surface because it has a tangent space at each vertex determined by its neighbor vertices. We develop a discrete surface theory on trivalent graphs, and define several geometric notions such as area, area variation formula, curvature, mean curvature. To abstract a continuum object hidden in the discrete surface, we introduce a subdivision method by applying the Goldberg-Coxeter subdivision, and discuss the convergence of a sequence of discrete surfaces defined inductively by the subdivision. We also study the limit set as the continuum geometric objects associated with the given discrete surface.

    We study geometry of trivalent discrete surfaces. In paricular, we define vertex-wise Gauss and mean curvatures for trivalent discrete surfaces in 3-dimensional Euclidean spaces. In our study, we take Carbon nanotubes, Fullerens, and Mackay structures, and we show that the Mackay structure of type P is vertex-wise negatively curved, which is called "a negatively graphene" in material sciences and organic chemistry.
    Moreover, we study subdivision of trivalent discrete surfaces. In particular, we show the Hausdorff convergence of the sequence of minimum energies of Mackay structures.
