Radial View of Continuous Cellular Automata
Continuous cellular automata (or coupled map lattices) are cellular automata where the state of the cells are real values in [0, 1] and the local transition rule is a real function...

How Neighborly Can a Centrally Symmetric Polytope Be?
Abstract. We show that there exist k-neighborly centrally symmetric ddimensional polytopes with 2(n + d) vertices, where k(d, n) = ,, d 1 + log((d + n)/d)

Perfect Dominating Sets in the Cartesian Products of Prime Cycles
We study the structure of a minimum dominating set of Cn 2n+1, the Cartesian product of n copies of the cycle of size 2n + 1, where 2n + 1 is a prime.
