We say that G (..) Sym(..) is transitive if G has just one orbit on , namely (..). If G is transitive on (..) and the only partitions of (..) preserved by G are (..) and (..), then we say that G is primitive. The O'Nan-Scott ...

A length over sequences of nucleotides is defined in similar way as is defined over permutations of the symmetric group. This length shows similar properties as the length for permutations and also shows some compatible ...

In this article, we analyze a recently proposed approach for the construction of antisymmetric functions for atomic and molecular systems. It is based on the assumption that the main problems with Hartree‐Fock wavefunctions ...

In the clinical electrophysiological practice, reading and comparing electroencephalographic (EEG) recordings are sometimes insufficient and take too much time. Tools coming from the information theory or nonlinear systems ...

Given a branched covering of degree d between closed surfaces, it determines a collection of partitions of d, the branch data. In this work we show that any branch data are realized by an indecomposable primitive branched ...
