On finite unions of ideals and cosets

Abstract

Although it is well known that the growth of Thompson's group F is exponential, the exact growth function is still unknown. Elements of its submonoid of positive words can be described using a binary rooted tree, whose norm can be computed assigning weights to each caret. Combining this fact with a combinatorial argument, the growth function of the submonoid is computed and thus providing a first step in the computation of the growth function of the group, as well as a lower bound for the growth rate for the group.

The deconfining phase transition in lattice quantum chromodynamics

We present a large-scale Monte Carlo calculation of the deconfining phase transition temperature in lattice quantum chromodynamics without fermions. Using the Wilson action, the transition temperature as a function of the lattice couplingg is consistent with scaling behavior dictated by the perturbativeα function for 6/g²>6.15. Speaker at the conference; on leave from CRIP, Budapest.

Electrical conductivity in very anisotropic conductors and semiconductors

Summary For very anisotropic metallic and semiconducting systems it is shown that the electrical conductivity in the direction of high effective mass decreases as the number of electrons in the conduction band grows. In the other directions the conductivity behaves normally.

Riassunto Si mostra che, per sistemi semiconduttori e metallici anisotropi, la conduttività elettrica nella direzione di massa altamente efficace diminuisce all'aumentare del numero di elettroni nella banda di conduzione. Nelle altre direzioni la conduttività si comporta normalmente.

Резюме Для очень анизотропных металлических и полупроводниковых систем показывается, что электропропроводность в направлении большой эффективной массы уменьшается, когда число электронов в зоне проводимости увеличивается. В других направлениях проводимость ведет себя нормальным образом.

     

Spectral methods for compressible reactive flows

High order simulations are necessary in order to capture fine details in resolving supersonic reactive flows. However, high Mach number compressible flows feature sharp gradients and discontinuities, which present a challenge to successful simulations using high order methods. Spectral methods have proven a powerful tool in simulation of incompressible turbulent flows, and recent advances allow the application of spectral methods to compressible reactive flows. We review the recent advances in the theory and application of spectral methods which allow stable computations of discontinuous phenomena, and the recovery of high order information via postprocessing, and present applications of high Mach number reactive flows.
