We investigate C-compact and relatively pseudocompact subsets of Tychonoff spaces with a special emphasis given to subsets of topological groups. It is shown that a relatively pseudocompact subset of a space X is C-compact in X, but not vice versa. If, however, X is a topological group, then these p
We construct frame starters in dicyclic groups Q2n, in particular we construct frame starters with adders in Q2q, where q = p n and p β‘ 3 mod 4 is a prime. We also deduce the existence of strong frame starters in Z2n for odd integers n whose prime factors are congruent with 1 modulo 4. The obtained
## Abstract Latin square type partial difference sets (PDS) are known to exist in __R__ Γ __R__ for various abelian __p__βgroups __R__ and in β€^__t__^. We construct a family of Latin square type PDS in β€^__t__^ Γ β€^2__nt__^~__p__~ using finite commutative chain rings. When __t__ is odd, the ambient
During the past decade, perfect, almost perfect and maximum nonlinear functions on ΓΏnite ΓΏelds have been thoroughly investigated. The main tool to investigate these functions is the Walsh-Hadamard transform. This is a special version of the more general discrete Fourier transform. It is the purpose
## Abstract In two groups of order 100 new difference sets are constructed. The existence of a difference set in one of them has not been known. The correspondence between a (100, 45, 20) symmetric design having regular automorphism group and a difference set with the same parameters has been used
