Structure of Genetic Algebras

Abstract

Verf. verallgemeinert Resultate von \textit{I. M. H. Etherington} [Proc. R. Soc. Edinb. 59, 242--258 (1939; Zbl 0027.29402; JFM 66.1209.01); Q. J. Math., Oxf. Ser. 12, 1--8 (1941; Zbl 0027.29401; JFM 67.0093.04); Proc. Edinb. Math. Soc., II. Ser. 6, 222--230 (1941; Zbl 0061.05302)] über gewisse in der Genetik auftretende nichtassoziative Algebren. Zu diesem Zweck verwendet er folgende Definition: Es sei \(\mathfrak A\) eine kommutative Algebra über dem Körper \(F\) und \(x\to \omega(x)\) ein Homomorphismus von \(\mathfrak A\) auf \(F\). \(\omega(x)\) heißt das \glqq Gewicht\grqq{} von \(x\). \(T(\mathfrak A)\) sei, die \glqq einhüllende\grqq{} Algebra der linearen Transformationen \(T\), die durch Rechtsmultiplikation der Elemente von \(\mathfrak A\) mit festen Elementen aus \(\mathfrak A\) erzeugt werden. Wenn die Koeffizienten des charakteristischen Polynoms \(\vert \lambda I - T\vert\) nur durch die Gewichte \(\omega(x_i)\) von den \(x_i\) abhängen, heißt \(\mathfrak A\) eine \glqq genetische\grqq{} Algebra. Diese Definition ermöglicht eine Strukturtheorie, in die die \glqq train\grqq{}-Algebren von Etherington sich einordnen.
