Tropical bounds for eigenvalues of matrices

open access: yes, 2013
We show that for all k = 1,...,n the absolute value of the product of the k largest eigenvalues of an n-by-n matrix A is bounded from above by the product of the k largest tropical eigenvalues of the matrix |A| (entrywise absolute value), up to a ...

Refinements of the Jensen Inequality and Estimates of the Jensen Gap Based on Interval‐Valued Functions

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12567-12576, August 2025.
ABSTRACT The significance of the Jensen inequality stems from its impactful and compelling outcomes. As a generalization of classical convexity, it plays a key role in deriving other well‐known inequalities such as Hermite–Hadamard, Hölder, Minkowski, arithmetic‐geometric, and Young's inequalities.

Ostrowski type inequalities for harmonically s-convex functions via fractional integrals [PDF]

open access: yes, 2013
In this paper, a new identity for fractional integrals is established. Then by making use of the established identity, some new Ostrowski type inequalities for harmonically s-convex functions via Riemann--Liouville fractional integral are established ...

A NOTE ON OSTROWSKI TYPE INEQUALITIES

open access: yesDemonstratio Mathematica, 2002
Summary: In the present note we establish two new integral inequalities of the Ostrowski type involving a function of one independent variable. The discrete analogues of the main results are also given.

Minimal limit key polynomials

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 5, May 2025.
Abstract In this paper, we extend the theory of minimal limit key polynomials of valuations on the polynomial ring K[x]$K[x]$. Minimal key polynomials are useful to describe, for instance, the defect of an extension of valued fields. We use the theory of cuts on ordered abelian groups to show that the previous results on bounded sets of key polynomials

High order Ostrowski type inequalities

open access: yesApplied Mathematics Letters, 2007
By using a generalized Euler type identity and the way of analysis, the Ostrowski inequality is extended for high-order derivatives. Some of the inequalities produced are sharp. Some applications to trapezoidal and mid-point rules are given. For some particular integers, some estimates are given with respect to \(L_\infty\)-norm.
