判定一个代数何时是演化代数

Determining when an algebra is an evolution algebra

Miguel D. Bustamante, Pauline Mellon, M. Victoria Velasco

摘要:

演化代数是描述非孟德尔遗传过程的非结合代数,与许多其他领域有联系。本文给出了给定代数$A$是演化代数的充要条件。我们证明了这个问题等价于所谓的$SDC$ $problem$,即给定矩阵集的$simultaneous$ $diagonalisation$ $via$ $congruence$。更精确地说,我们证明了一个$n$维代数$A$是一个演化代数当且仅当,一定的一组$n$对称$n\times n$矩阵$\{M_{1}, \ldots, M_{n}\}$描述的产品的$A$是$SDC$。我们应用这个特性表明,虽然某些经典的遗传代数(代表孟德尔和auto-tetraploid遗传)本身不是进化代数,任意小的扰动,这些是进化代数。这是有趣的,因为进化代数模型无性繁殖不同于经典的。

英文摘要:

Evolution algebras are non-associative algebras that describe non-Mendelian hereditary processes and have connections with many other areas. In this paper we obtain necessary and sufficient conditions for a given algebra $A$ to be an evolution algebra. We prove that the problem is equivalent to the so-called $SDC$ $problem$, that is, the $simultaneous$ $diagonalisation$ $via$ $congruence$ of a given set of matrices. More precisely we show that an $n$-dimensional algebra $A$ is an evolution algebra if, and only if, a certain set of $n$ symmetric $n\times n$ matrices $\{M_{1}, \ldots, M_{n}\}$ describing the product of $A$ are $SDC$. We apply this characterisation to show that while certain classical genetic algebras (representing Mendelian and auto-tetraploid inheritance) are not themselves evolution algebras, arbitrarily small perturbations of these are evolution algebras. This is intriguing as evolution algebras model asexual reproduction unlike the classical ones.
