Representations Of Finite Groups And Cuntz-Krieger Algebras, M Mann, Iain Raeburn, C Sutherland Jan 1992

Representations Of Finite Groups And Cuntz-Krieger Algebras, M Mann, Iain Raeburn, C Sutherland

Faculty of Engineering and Information Sciences - Papers: Part A

We investigate the structure of the C*-algebras (9ρ constructed by Doplicher and Roberts from the intertwining operators between the tensor powers of a representation ρ of a compact group. We show that each Doplicher-Roberts algebra is isomorphic to a corner in the Cuntz-Krieger algebra (9A of a {0,1}-matrix A = Aρ associated to ρ. When the group is finite, we can then use Cuntz's calculation of the K-theory of (9A to compute K*((9ρ).


Zeckendorf Representations Using Negative Fibonacci Numbers, M W. Bunder Jan 1992

Zeckendorf Representations Using Negative Fibonacci Numbers, M W. Bunder

Faculty of Engineering and Information Sciences - Papers: Part A

It is well known that every positive integer can be represented uniquely as a sum of distinct, nonconsecutive Fibonacci numbers (see, e.g., Brown [1]. This representation is called the Zeckendorf representation of the positive integer. Other Zeckendorf-type representations where the Fibonacci numbers are not necessarily consecutive are possible. Brown [2] considers one where a maximal number of distinct Fibonacci numbers are used rather than a minimal number.

The Response To Selection Of Different Procedures For The Analysis Of Early Generation Variety Trials, Brian R. Cullis, A. C. Gleeson, F. M. Thomson Jan 1992

The Response To Selection Of Different Procedures For The Analysis Of Early Generation Variety Trials, Brian R. Cullis, A. C. Gleeson, F. M. Thomson

Faculty of Engineering and Information Sciences - Papers: Part A

A simulation study was conducted to determine the relative response to selection of a one-dimensional spatial analysis of field experiments (SAFE) specifically adapted for early generation trials. The primary purpose of the analysis in these trials is to obtain accurate estimates of genotypic effects of the unreplicated test lines by adjusting for local variation, using either the yields of all neighbouring plots or the yields of neighbouring plots of (replicated) check varieties. The response to selection of the SAFE analysis, relative to the use of unadjusted yields of test line plots, was consistently greater than the relative response to selection ...
