The integral part of a nonlinear form with a square, a cube and a biquadrate

open access: yesOpen Mathematics, 2020
In this paper, we show that if λ1,λ2,λ3{\lambda }_{1},{\lambda }_{2},{\lambda }_{3} are non-zero real numbers, and at least one of the numbers λ1,λ2,λ3{\lambda }_{1},{\lambda }_{2},{\lambda }_{3} is irrational, then the integer parts of λ1n12+λ2n23+λ3n34{

Observation of vibrating systems at different time instants

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
In this paper, we obtain new observability inequalities for the vibrating string. This work was motivated by a recent paper of A. Szijártó and J.

A note on Diophantine inequalities in function fields [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
We will discuss how the Bentkus–Götze–Freeman variant of the Davenport–Heilbronn circle method can be used to study 𝔽_q[t] solutions to inequalities of the form ord(λ₁p₁ᵏ+...+λₛpₛᵏ-γ)

Rational points close to non-singular algebraic curves [Elektronisk resurs]

open access: yes, 2023
We study the density of solutions to Diophantine inequalities involving non-singular ternary forms, or equivalently, the density of rational points close to non-singular plane algebraic ...

Local Diophantine Nullstellen inequalities [PDF]

open access: yesJournal of the American Mathematical Society, 1988
The main result of this paper is as follows. Let \(P_1,\ldots, P_n\) be polynomials of total degree at most \(D\) in \(x_1,\ldots,x_m\), with rational integer coefficients of absolute values at most \(H\).

Random Diophantine inequalities of additive type

open access: yes, 2012
Using the Davenport–Heilbronn circle method, we show that for almost all additive Diophantine inequalities of degree k in more than 2k variables the expected asymptotic formula for the density of solutions holds ...

On the Frobenius number of a modular Diophantine inequality [PDF]

open access: yesMathematica Bohemica, 2008
Summary: We present an algorithm for computing the greatest integer that is not a solution of the modular Diophantine inequality \(ax\bmod b\leq x\), with complexity similar to the complexity of the Euclid algorithm for computing the greatest common divisor of two integers.
