Group divisible designs with two associate classes
(University of Canterbury. Dept. of Mathematics, 1995)
The work in this research report was done while visiting The University of Canterbury, and was completed jointly in cooperation with H.L. Fu and D. Sarvate. These results follow upon previous efforts where we were ...
Determinantal forms for symplectic and orthogonal Schur functions
(University of Canterbury. Dept. of Mathematics, 1994)
Symplectic and orthogonal Schur functions can be defined combinatorially in a manner similar to the classical Schur functions. This paper demonstrates that they can also be expressed as determinants. These determinants ...
On weakly mixing transformation semigroups
(University of Canterbury. Dept. of Mathematics, 1982)
A generalization of the classical ergodic mixing theorem is given, valid for arbitrary topological semigroups. Conditions under which the tensor product of two representations has no fixed points are obtained and these ...
