Non-Equilibrium Phase Transitionsix, the Laplacian matrix and the Colin de Verdière matrix. In examples we show their possibilities and limits of applicability. We suggest a new matrix that reproduces well the same structures and those ones which were not drawn by the previous matrices.

Theoretical and Mathematical Physicsfor coding and ordering Kekulé structures of cata-condensed benzenoids. In the case of peri-condensed benzenoids the numeric code of Kekulé structures is not discriminative enough since there are Kekulé structures with identical numeric codes. In that case an additional code is needed, and here we suggest the perimeter code.

Empirical Study of Diameters of Fullerene Graphs,enes with large diameters are exceedingly rare. Our results suggest that there is a linear upper bound on the diamater of the fullerenes with isolated pentagons and that the minimum diameter is achieved on an isomer with isolated pentagons for large enough number of vertices.

Stiff Polymers at Ultralow Temperatures, regime their fluctuations show quantum behavior. This is calculated here for the second and fourth moments of the end-to-end distribution in the large stiffness expansion. The result should soon be measurable.
