Wormhole solutions with a polynomial equation-of-state and minimal violation of the null energy condition [PDF]
European Physical Journal C: Particles and Fields, 2020 This paper discusses wormholes supported by general equation-of-state , resulting in a significant combination of the linear equation-of-state and some other models. Wormhole with a quadratic equation-of-state is studied as a particular example.

On refined neutrosophic finite p-group [PDF]
Journal of Fuzzy Extension and Applications, 2023 The neutrosophic automorphisms of a neutrosophic groups G (I) , denoted by Aut(G (I)) is a neu-trosophic group under the usual mapping composition. It is a permutation of G (I) which is also a neutrosophic homomorphism. Moreover, suppose that X1 = X(G (

The minimal exponent and k-rationality for local complete intersections [PDF]
Journal de l'École polytechnique. Mathématiques, 2022 We show that if $Z$ is a local complete intersection subvariety of a smooth complex variety $X$, of pure codimension $r$, then $Z$ has $k$-rational singularities if and only if $\widetilde{\alpha}(Z)>k+r$, where $\widetilde{\alpha}(Z)$ is the minimal ...

Groups with Subnormal Deviation
Mathematics, 2023 The structure of groups which are rich in subnormal subgroups has been investigated by several authors. Here, we prove that if a periodic soluble group G has subnormal deviation, which means that the set of its non-subnormal subgroups satisfies a very ...

Groups with many Subgroups which are Commensurable with some Normal Subgroup [PDF]
Advances in Group Theory and Applications, 2019 A subgroup H of a group G is called commensurable with a normal subgroup (cn) if there is N C G such that |HN/(H ∩ N)| is finite. We characterize generalized radical groups G which have one of the following finiteness conditions: (A) the minimal ...

On Minimal Non-Soluble Groups, the Normalizer Condition and McLain Groups [PDF]
Advances in Group Theory and Applications, 2017 We prove that a minimal non-soluble ($MN\mathfrak{S}$ in short) Fitting $p$-group $G$ has a proper subgroup $K$ such that for every proper subgroup $R$ of $G$ containing $K$, we have $N_G(R) > R$.

Journal of Functional Analysis, 2022 We study minimal integrability conditions via Luxemburg-type expressions with respect to generalized oscillations that imply the membership of a given function $f$ to the space BMO. Our method is simple, sharp and flexible enough to be adapted to several different settings, like spaces of homogeneous type, non doubling measures on $\mathbb{R}^n$ and ...

Minimal conditions on Clifford semigroupcongruences [PDF]
International Journal of Mathematics and Mathematical Sciences, 2006 A known result in groups concerning the inheritance of minimal conditions on normal subgroups by subgroups with finite indexes is extended to semilattices of groups [E(S), Se, ϕe,f] with identities in which all ϕe,f are epimorphisms (called q partial groups). Formulation of this result in terms of q congruences is also obtained.
