A recente publicação de Naturalism Against Nature: Kinship and Degeneracy inFin-de-siècle Portugal and Brazil traz como principal proposta revisitar obras eautores relevantes no escopo do Realismo-Naturalismo em Portugal e Brasil. O objetivo de David J. B... see more

In 2007 Matamala proved that if G is a simple graph with maximum degree ? = 3 not containing K?+1 as a subgraph and s, t are positive integers such that s+t = ?, then the vertex set of G admits a partition (S,T) such that G[S] is a maximum order (s-1... see more

Degeneracy can cause enormous problems when solving large scale linear programming problems. This is not only because there is a possibility that the problem can cycle, but also because a large number of iterations can be executed that do not improve the ... see more

Degeneracy may cause various computing and other complications in any mathematical programming problem of the kind where the constraint set defines a convex polyhedral set (particularly, a polytope). In order to be able to study various seemingly independ... see more

This article provides an alternative reading of one of Ec¸a’s most widely read and discussed texts, Os Maias, by challenging the common interpretation of the text as primarily about the incestuous relationship between the siblings Carlos and Maria Eduarda... see more

Two graphs having the same number of vertices connected in the same way are said to be isomorphic. Topological matrices representing such graphs will have the same eigen value spectrum. Hence isomorphic graphs are also known as co spectral or iso spectral... see more
