A local limit theorem assuming finite second moments via Stein’s method

open access: yesArab Journal of Basic and Applied Sciences
Let [Formula: see text] be independent but not necessarily identically distributed integer-valued random variables and let [Formula: see text] Estimation of the point probabilities [Formula: see text] is a common problem that occurs in many applied ...

Moments, sums of squares, and tropicalization

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 4, October 2025.
Abstract We use tropicalization to study the duals to cones of nonnegative polynomials and sums of squares on a semialgebraic set S$S$. The truncated cones of moments of measures supported on the set S$S$ are dual to nonnegative polynomials on S$S$, while “pseudomoments” are dual to sums of squares approximations to nonnegative polynomials.

On the approximation of functions by means of the operators of binomial type of Tiberiu Popoviciu

open access: yesJournal of Numerical Analysis and Approximation Theory, 2001
In 1931, Tiberiu Popoviciu has initiated a procedure for the construction of sequences of linear positive operators of approximation. By using the theory of polynomials of binomial type \((p_m)\) he has associated to a function \(f\in C[0,1]\) a linear ...

Moments of the Riemann zeta function at its local extrema

open access: yesMathematika, Volume 71, Issue 4, October 2025.
Abstract Conrey, Ghosh and Gonek studied the first moment of the derivative of the Riemann zeta function evaluated at the non‐trivial zeros of the zeta function, resolving a problem known as Shanks' conjecture. Conrey and Ghosh studied the second moment of the Riemann zeta function evaluated at its local extrema along the critical line to leading order.

Geometric inequalities, stability results and Kendall's problem in spherical space

open access: yesMathematika, Volume 71, Issue 4, October 2025.
Abstract In Euclidean space, the asymptotic shape of large cells in various types of Poisson‐driven random tessellations has been the subject of a famous conjecture due to David Kendall. Since shape is a geometric concept and large cells are identified by means of geometric size functionals, the resolution of the conjecture is inevitably connected with
