Lossless Data Compression Using Optimal Tree Machines
We discuss a lossless data compression system that uses fixed Tree Machines to encode data. The idea is to create a sequence of Tree Machines and a robust escape method aimed at p...

Real, Tight Frames with Maximal Robustness to Erasures
Motivated by the use of frames for robust transmission over the Internet, we present a first systematic construction of real tight frames with maximum robustness to erasures. We a...

Extensions of Generalized Product Caps
We give some variants of a new construction for caps. As an application of these constructions we obtain a 1216?cap in PG(9, 3) a 6464?cap in PG(11, 3) and several caps in ternary...

Towards a Uniform Description of Several Group Based Cryptographic Primitives
The public key cryptosystems MST1 and MST2 make use of certain kinds of factorizations of finite groups. We show that generalizing such factorizations to infinite groups allows a ...
