چکیده
A lattice is called well-rounded, if its lattice vectors of minimal length span the ambient space. We show that there are interesting connections between the existence of well-rounded sublattices and coincidence site lattices (CSLs). Furthermore, we count the number of well-rounded sublattices for several planar lattices and give their asymptotic behaviour.

Simple finite dimensional Kantor triple systems are classified in terms of Satake diagrams. We prove that every simple linearly compact Kantor triple system is finite dimensional and provide an explicit presentation of all the classical and exceptional systems.

Let A be a set of positive numbers. A graph G is called an Aembeddable graph in R if the vertices of G can be positioned in R so that the distance between endpoints of any edge is an element of A. We consider the computational problem of recognizing A-embeddable graphs in R1 and classify all finite sets A by complexity of this problem in several natural variations.

We report the result from a search for bursts of gravitational waves using data collected by the cryogenic resonant detectors EXPLORER and NAUTILUS during the year 2001, for a total measuring time of 90 days. With these data we repeated the coincidence search performed on the 1998 data (which showed a small coincidence excess) applying data analysis algorithms based on known physical characteri...

A Smarandache multi-space is a union of n spaces A 1 , A 2 , · · · , A n with some additional conditions holding. Combining Smarandache multi-spaces with classical metric spaces, the conception of multi-metric space is introduced. Some characteristics of a multi-metric space are obtained and Banach's fixed-point theorem is generalized in this paper.
