A New Identity Involving the Chebyshev Polynomials

Mathematics, 2018
In this paper, firstly, we introduced a second order non-linear recursive sequence, then we use this sequence and the combinatorial methods to perform a deep study on the computational problem concerning one kind sums, which includes the Chebyshev ...

MA‐LCPPA: A Multi‐Aggregator Lattice‐Based Conditional Privacy‐Preserving Authentication Scheme for Scalable and Quantum‐Secure VANETs

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper addresses the limitations of existing conditional privacy‐preserving authentication (CPPA) schemes in vehicular ad hoc networks (VANETs), which are either computationally heavy or vulnerable to quantum attacks. It proposes a multi‐aggregator lattice‐based CPPA (MA‐LCPPA) framework that distributes verification across multiple roadside units ...

Mechanistic insights into the anion‐driven suppression of the initial cement reaction of tricalcium aluminate

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The hydration process of ordinary Portland cement (OPC) involves intricate interactions among ions in the pore solution, dissolving clinker phases, and precipitating hydrates. Tricalcium aluminate (C3A${\rm C}_3{\rm A}$) shows the highest reactivity of the cement clinker phases during the initial hydration stages of OPC. The kinetic control of

The sharp upper bound for generation of linear semigroups by higher order equations with fractional powers

Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract In this paper, we consider a class of higher‐order equations and show a sharp upper bound on fractional powers of unbounded linear operators associated with higher‐order abstract equations in Hilbert spaces.

Zeros of multiple orthogonal polynomials: location and interlacing

Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract We prove a criterion for the possible locations of zeros of type I and type II multiple orthogonal polynomials in terms of normality of degree 1 Christoffel transforms. We provide another criterion in terms of degree 2 Christoffel transforms for establishing zero interlacing of the neighboring multiple orthogonal polynomials of type I and type
