Abstract In topology optimization the goal is to find the ideal material distribution in a domain subject to external forces. The structure is optimal if it has the highest possible stiffness. A volume constraint ensures filigree structures, which ar

This paper is devoted to the study of injectivity for ordered universal algebras. We first characterize injectives in the category OALΣ⩽$\begin{array}{} \displaystyle {\mathsf{OAL}_{{\it\Sigma}}^{\leqslant}} \end{array}$ of ordered Σ-algebras wit

Degenerate solutions to the Yang-Baxter equation are studied by means of associated semibraces and groups. Using a characterization in terms of cycle sets, a non-degenerate part is separated from a purely degenerate one. More precisely, any cycle set

Measure and integration theory for finitely additive measures, including vector-valued measures, is shown to be essentially covered by a class of commutative L-algebras, called measurable algebras. The domain and range of any measure is a commutative

More than 30 years ago, M. Auslander proved, for Cohen–Macaulay orders over a complete regular local ring of dimension d, that existence of almost split sequences is equivalent to the presence of an isolated singularity. CM-finite Cohen–Macaulay

Let a norm on the set M n of real or complex n-by-n matrices be given. We investigate the question of finding the largest constants α n and β n such that for each A ∈ M n the average of the norms of its (n−1)-by-(n−1) principal submatrices is

It is shown that a general concept of Morita duality between abelian categories with no generating hypothesis for reflexive objects is completely described by a special class of quasi-abelian categories, called ample Morita categories. The duality ta
