Quasinormal modes of boson stars

Physical Review D, 1994
We investigate nonradial oscillations of a boson star by taking into account the emission of the gravitational waves in the framework of general relativity. Since only even-parity modes of perturbations couple to the gravitational waves, we analyze these modes.

Quasinormality and fuzzy subgroups

Fuzzy Sets and Systems, 1993
The paper deals with fuzzy subgroups of a group in order to obtain fuzzy extensions of normal, quasinormal, core-free and Sylow subgroups. Some properties of the notions introduced are presented. Another consideration of fuzzy normal subgroups was recently published by \textit{Y. Suzuki} [J. Fuzzy Math. 2, 1-15 (1994; Zbl 0803.20060)].

ON -QUASINORMAL SUBGROUPS OF FINITE GROUPS

Bulletin of the Australian Mathematical Society, 2018
Let $G$ be a finite group and $\unicode[STIX]{x1D70E}=\{\unicode[STIX]{x1D70E}_{i}\mid i\in I\}$ some partition of the set of all primes $\mathbb{P}$ , that is, $\mathbb{P}=\bigcup _{i\in I}\unicode[STIX]{x1D70E}_{i}$

Quasinormal subgroups of infinite groups

Ricerche di Matematica, 2014
It is well-known that if \(G\) is a finite group and \(H\) is a quasinormal subgroup of \(G\), that is, \(H\) satisfies \(HK=KH\) for every \(K\leq G\), then \(H\) is subnormal in \(G\), \(H/H_G\) is nilpotent, and it even is contained in the hypercentre of \(G/H_G\).
