On hyperovals of polar spaces
We derive lower and upper bounds for the size of a hyperoval of a finite polar space of rank r {2, 3}. We give a computer-free proof for the uniqueness, up to isomorphism, of the...

Vertex Numbers of Weighted Faces in Poisson Hyperplane Mosaics
In the random mosaic generated by a stationary Poisson hyperplane process in Rd , we consider the typical k-face weighted by the j-dimensional volume of the j-skeleton (0 j k d)...

T-shift synchronization codes
In this paper we give a construction of T-shift synchronization codes, i.e. block codes capable of correcting synchronization shifts of length at most T in either direction (left ...

Infinite State Model-Checking of Propositional Dynamic Logics
Model-checking problems for PDL (propositional dynamic logic) and its extension PDL (which includes the intersection operator on programs) over various classes of infinite state sy...
