On a measure of noncompactness in the space of regulated functions and its applications

Advances in Nonlinear Analysis, 2018
In this paper we formulate a criterion for relative compactness in the space of functions regulated on a bounded and closed interval. We prove that the mentioned criterion is equivalent to a known criterion obtained earlier by D.

The systole of random hyperbolic 3‐manifolds

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract We study the systole of a model of random hyperbolic 3‐manifolds introduced in Petri and Raimbault [Comment. Math. Helv. 97 (2022), no. 4, 729–768], answering a question posed in that same article. These are compact manifolds with boundary constructed by randomly gluing truncated tetrahedra along their faces.

Conformable functional evolution equations with nonlocal conditions in Banach spaces [PDF]

Surveys in Mathematics and its Applications, 2023
In this paper, we study semilinear conformable fractional evolution equations with finite delay subjected to nonlocal initial conditions in an arbitrary Banach space.

Experimental investigations and design of precast concrete‐filled steel corrugated sheet slender columns with intermediate connection

Structural Concrete, Volume 27, Issue 1, Page 193-210, February 2026.
Abstract Concrete‐filled steel corrugated sheet (CFSCS) offers confinement to the core concrete while the outer galvanized corrugated steel sheet (GCSS) offers excellent corrosion resistance. Application of precast multiple CFSCS columns connected through high‐performance concrete (HPC) in constructing a slender column offers ease of construction while

Asymptotic behaviour of solutions of nonlinear delay difference equations in Banach spaces

International Journal of Mathematics and Mathematical Sciences, 2005
We consider the second-order nonlinear difference equations of the form Δ(rn−1Δxn−1)+pnf(xn−k)=hn. We show that there exists a solution (xn), which possesses the asymptotic behaviour ‖xn−a∑j=0n−1(1/rj)+b‖=o(1), a,b∈ℝ. In this paper, we extend the results

Controllability for a new class of fractional neutral integro-differential evolution equations with infinite delay and nonlocal conditions

Advances in Difference Equations, 2017
In this paper, we apply the fractional calculus and a suitable fixed point theorem with the measure of noncompactness to give the sufficient conditions of the controllability for a new class of fractional neutral integro-differential evolution systems ...

On interpolation of the measure of noncompactness [PDF]

Proceedings of the Estonian Academy of Sciences. Physics. Mathematics, 2006
We revised the known results on interpolation of the measure of noncompactness and we announce a new approach to establishing the interpolation formula for the real method.

Plastic Behavior and Design Methodology for Curved Members in Seismic Applications

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
This study investigated the plastic behavior of curved members through static analysis and extensive parametric studies, focusing on initial elastic stiffness, plastic strength, slenderness effects, and section compactness. Estimation equations were developed and validated, contributing to the development of a connection design methodology that ...

A Study of Positive Solutions for Semilinear Fractional Measure Driven Functional Differential Equations in Banach Spaces

Mathematics
In this paper, we deal with the delayed measure differential equations with nonlocal conditions via measure of noncompactness in ordered Banach spaces. Combining (β,γk)-resolvent family, regulated functions and fixed point theorem with respect to convex ...

On modulus of noncompact convexity for a strictly minimalizable measure of noncompactness

Gulf Journal of Mathematics, 2014
In this paper we consider modulus of noncompact convexity ΔX,φ associated with the strictly minimalizable measure of noncompactness φ. We also give some its properties and show its continuity on the interval [0, φ(BX)).
