Simulations of Disordered Bosons on Hyper-Cubic Lattices
We address computational issues relevant to the study of disordered quantum mechanical systems at very low temperatures. As an example we consider the disordered BoseHubbard model...

A Grid-Enabled Lattice-Boltzmann-Based Modelling System
Lattice-Boltzmann (LB) methods are a well-known technique in the context of computational fluid dynamics. By nature, they can easily be parallelized but their adaptation to the Gr...

The Shortest Vector in a Lattice is Hard to Approximate to Within Some Constant
We show that approximating the shortest vector problem (in any p norm) to within any constant factor less than p 2 is hard for NP under reverse unfaithful random reductions with i...

Lattices on simplicial partitions
In this paper, (d + 1)-pencil lattices on simplicial partitions in Rd are studied. The barycentric approach naturally extends the lattice from a simplex to a simplicial partition,...

Free MV-algebras
We describe n-generated free MV -algebras as MV-algebras having the lattice reduct which is a direct limit in the category of distributive lattices.
