Real elements and p-nilpotence of finite groups
Ballester Bolinches, Adolfo; Esteban Romero, Ramón; Ezquerro Marín, Luis Miguel (Aracne, 2016)
Artículo / Artikulua
Our first main result proves that every element of order 4 of a Sylow 2-subgroup S of a minimal non-2-nilpotent group G, is a real element of S. This allows to give a character-free proof of a theorem due to Isaacs and ... -

Reduction of the size of L-fuzzy contexts. A tool for differential diagnoses of diseases
Alcalde, Cristina; Burusco Juandeaburre, Ana (Taylor & Francis, 2019)
Artículo / Artikulua
Information extraction from an L-fuzzy context becomes a hard problem when we work with a large set of objects and/or attributes. The goal of this paper is to present two different and complementary techniques to reduce ... -
Reeb’s theorem and periodic orbits for a rotating Hénon–Heiles potential
Lanchares, Víctor; Pascual, Ana Isabel; Iñarrea, Manuel; Salas, José Pablo; Palacián Subiela, Jesús Francisco ; Yanguas Sayas, Patricia (Springer, 2019)
Artículo / Artikulua
We apply Reeb’s theorem to prove the existence of periodic orbits in the rotating Hénon– Heiles system. To this end, a sort of detuned normal form is calculated that yields a reduced system with at most four non degenerate ... -
