Two-dimensional perfect evolution algebras over domains. J Algebr Comb 58, 569–587 (2023). https://doi.org/10.1007/s10801-022-01196-1 https://hdl.handle.net/10630/29730 10.1007/s10801-022-01196-1 We will study evolution algebras A that are free modules of dimension two over domains. We start by making some general considerations about algebras over domains: They are sandwiched between a certain essential D-submodule and its scalar extension over the field of fractions of the domain. We introduce the notion of quasiper- fect algebras and we characterize the perfect and quasiperfect evolution algebras in terms of the determinant of its structure matrix. We classify the two-dimensional perfect evolution algebras over domains parametrizing the isomorphism classes by a convenient moduli set. eng open access Álgebra Two-dimensional perfect evolution algebras over domains journal article
