Tight Bounds on the Round Complexity of Distributed 1-Solvable Tasks
A distributed task T is 1-solvable if there exists a protocol that solves it in the presence of (at most) one crash failure. A precise characterization of the 1-solvable tasks was...

The cell probe complexity of dynamic range counting
In this paper we develop a new technique for proving lower bounds on the update time and query time of dynamic data structures in the cell probe model. With this technique, we pro...

Polynomial-time algorithm for Hilbert series of Borel type ideals
In this paper, it is shown that the Hilbert series of a Borel type ideal may be computed within a complexity which is polynomial in Dn where n + 1 is the number of unknowns and D ...

Ubiquitous Parameterization - Invitation to Fixed-Parameter Algorithms
Abstract. Problem parameters are ubiquitous. In every area of computer science, we find all kinds of “special aspects” to the problems encountered. Hence, the study of paramet...
