Proper 3‐realizability and second cohomology of groups on two generators of finite order
Bulletin of the London Mathematical Society, Volume 58, Issue 7, July 2026.Abstract Given an (infinite) finitely generated group G$G$, its first cohomology group H1(G;ZG)$H^1(G;{\mathbb {Z}}G)$ is free abelian and “counts” the number of ends of G$G$ which equals 1+rank(H1(G;ZG))$1 + rank (H^1(G;{\mathbb {Z}}G))$. The question whether or not for every finitely presented group G$G$ its second cohomology group H2(G;ZG)$H^2(G ...

Hausdorff Measure of Noncompactness of Matrix Mappings on Certain Difference Sequence Spaces [PDF]
, 2023 The well-known difference sequence spaces were introduced by Kızmaz [16] in 1981 and have been generalized by many authors uptill now. These spaces were extended for the first time by Sarıgöl [30] to the sequence spaces l∞(∆q), c(∆q) and c0(∆q).

Solvability of integral equations via the technique of measures of noncompactness
Miskolc Mathematical NotesMotivated by the work of [Mohammadi et al., Mathematics, 2019, 7, 575.], we extend here Darbo’s fixed point theorem in a Banach space using the combined technique of Wardowski-Mizoguchi-Takahashi contraction.

An elegant model of the geodesic flow on the modular surface
Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.Abstract Caroline Series' [The modular surface and continued fractions, J. Lond. Math. Soc. (2), 31, no. 1, (1985), 69–80] gives a clear framework linking, in a deceptively simple way, the dynamics of the geodesic flow on the modular surface with the dynamics of the regular continued fraction, through a well‐chosen symbolic coding.

Continuity of modulus of noncompact convexity for minimalizable measures of noncompactness
, 2015 We consider the modulus of noncompact convexity $Δ_{X,ϕ}(\varepsilon)$ associated with the minimalizable measure of noncompactness $ϕ$. We present some properties of this modulus, while the main result of this paper is showing that $Δ_{X,ϕ}(\varepsilon)$ is a subhomogenous and continuous function on $[0,ϕ(\bar{B}_X))$ for an arbitrary minimalizable ...

ChemBioChem, Volume 27, Issue 11, 15 June 2026.This review reconsiders the amyloid cascade by placing lipid dynamics at its core. It shows that free lipids, governed by critical micellar concentration, act as pathological chaperones that redirect amyloid aggregation toward membrane‐damaging species.

Application of Measure of Noncompactness to Infinite Systems of Differential Equations [PDF]
, 2013 In this paper we determine theHausdorff measure of noncompactness on the sequence space n(ϕ) ofW. L. C. Sargent. Further we apply the technique of measures of noncompactness to the theory of infinite systems of differential equations in the Banach ...
