The paper investigates the synchronization of a network of identical linear state-space models under a possibly time-varying and directed interconnection structure. The main resul...
It is shown that polynomial (or rational) parametric surfaces with a linear field of normal vectors are dual to graphs bivariate polynomials (or rational functions). We discuss th...

Graphs are widely used for information visualization purposes, since they provide a natural and intuitive tation of complex abstract structures. The automatic generation of drawing...
We study the complexity of restricted versions of s-t-connectivity, which is the standard complete problem for NL. In particular, we focus on different classes of planar graphs, o...
