Oller-Marcén, Antonio M. Tying up baric algebras. (English) Zbl 1299.17030 Math. Slovaca 62, No. 5, 865-874 (2012). Summary: Given two baric algebras \((A_1,\omega _1)\) and \((A_2,\omega _2)\) we describe a way to define a new baric algebra structure over the vector space \(A_1\oplus A_2\), which we shall denote \((A_1\bowtie A_2,\omega _1\bowtie \omega _2)\). We present some easy properties of this construction and we show that in the commutative and unital case it preserves indecomposability. Algebras of the form \(A_1\bowtie A_2\) in the associative, coutable-dimensional, zero-characteristic case are classified.
