An X-ray study of isomorphism in simple organo-metallic series. — Part I. The tetraphenyls
The present paper deals with a preliminary X-ray study of the isomorphous series of organo-metallic compounds formed by combining a fourth-group clement with four phenyl radicals, the resulting compounds being the tetraphenyls of carbon, silicon ...

Minimal Triangulations of Manifolds
In this survey article, we are interested on minimal triangulations of closed pl manifolds. We present a brief survey on the works done in last 25 years on the following: (i) Finding the minimal number of vertices required to triangulate a given pl ...

Periodic diffraction patterns for 1D quasicrystals
A simple model of 1D structure based on a Fibonacci sequence with variable atomic spacings is proposed. The model allows for observation of the continuous transition between periodic and non-periodic diffraction patterns.

Quantum extended crystal PDE's
Our recent results on {\em extended crystal PDE's} are generalized to PDE's in the category $\mathfrak{Q}_S$ of quantum supermanifolds. Then obstructions to the existence of global quantum smooth solutions for such equations are obtained, by using ...
