Diamond Twin

Toshikazu Sunada

As noticed in 2006 by the author of the present article, the hypothetical crystal---described by crystallographer F. Laves (1932) for the first time and designated ``Laves' graph o…

From Euclid to Riemann and Beyond

Toshikazu Sunada

The purpose of this essay is to trace the historical development of geometry while focusing on how we acquired mathematical tools for describing the "shape of the universe." More s…

Generalized Riemann sums

Toshikazu Sunada

The primary aim of this chapter is, commemorating the 150th anniversary of Riemann's death, to explain how the idea of {\it Riemann sum} is linked to other branches of mathematics.…

Topics on mathematical crystallography

Toshikazu Sunada

In July 2012 the General Assembly of the United Nations resolved that 2014 should be the International Year of Crystallography, 100 years since the award of the Nobel Prize for the…

Standard 2D Crystalline Patterns and Rational Points in Complex Quadrics

Toshikazu Sunada

A certain Diophantine problem and 2D crystallography are linked through the notion of standard realizations which was introduced originally in the study of random walks. In the dis…

Asymptotic behavior of quantum walks on the line

Toshikazu Sunada, Tatsuya Tate

This paper gives various asymptotic formulae for the transition probability associated with discrete time quantum walks on the real line. The formulae depend heavily on the `normal…

Geometric Theory of Lattice Vibrations and Specific Heat

Mikhail Shubin, Toshikazu Sunada

We discuss, from a geometric standpoint, the specific heat of a solid. This is a classical subject in solid state physics which dates back to a pioneering work by Einstein (1907) a…
