On the Real Stability Radius for Some Classes of Matrices,2020)). With the use of the elimination of variables procedure we reduce the problem to the univariate equation solving. The structure of the destabilizing perturbation matrix is also discussed as well as cases of symmetric and orthogonal matrices where the stability radius can be explicitly express

Decoupling Multivariate Fractions,orithm builds a tree where internal nodes are operators, and leaves are fractions depending on pairwise disjoint sets of variables. The motivation of this work is to obtain compact forms of fractions, which are more readable and meaningful for the user or the modeler, and better suited for interval

On the Pseudo-Periodicity of the Integer Hull of Parametric Convex Polygons,ger vector. The coordinates . of . are treated as parameters while the coefficients of . have fixed values. We observe that for every ., there exists a positive integer . so that, when each . is large enough, the vertex sets . and . of the respective integer hulls of . and ., respectively, are in a

Simplification of Nested Real Radicals Revisited,fields is somewhat easier to study (at least, from theoretical point of view). In particular, an efficient (i.e., a polynomial-time) algorithm of simplification of at most doubly nested radicals is known. However, this algorithm does not guarantee complete simplification for the case of radicals wit

,Testing Binomiality of Chemical Reaction Networks Using Comprehensive Gröbner Systems, on the parameters such that the steady state ideal of a chemical reaction network is binomial under every specialisation of the parameters if the conditions on the parameters hold. We approach the binomiality problem using Comprehensive Gröbner systems. Considering rate constants as parameters, we
