The Class of Neat Reducts is Not Elementary
- …We solve a problem of Tarski, and his co-authors Andreka, Henkin, Monk, and Nemeti. We show that for any pair of ordinals 1 < < , the class of -dimensional neat reducts of -dimensional cylindric algebras is not elementary. The construction we use when is infinite also settles a conjecture of Tarski …

On Amalgamation of Reducts of Polyadic Algebras
- …Following research initiated by Tarski,Craig and Nemeti, and further pursued by Sain, we show that for certain subsets G of !, G polyadic algebras have the strong amalgamation property. G polyadic algebras are obtained by restricting (the similarity type) and axiomatization of !-dimensional polya…

Autonomous Decentralized Community Communication Technology for Assuring Information Dissemination
- …The enormous growth and the dynamism of the Internet initiated various new trends that reflects the need for powerful communication methods than the simpler client/server and Peer-to-Peer architecture. Despite their great potential, these systems still lack e#cient data dissemination mechanisms. The…
