Positivity and polynomial decay of energies for square-field operators [PDF]
We show that for a general Markov generator the associated square-field (or carré du champs) operator and all their iterations are positive. The proof is based on an interpolation between the operators involving the generator and their semigroups, and an

Dynamics of a new thermoelastic Timoshenko system with second sound
This work studies the optimal and general stability of a thermoelastic Timoshenko system with second sound. More succinctly, under some assumptions on the parameters of the system, we derive an optimal and general decay result for the solution energy of ...

Stability Result for a Kirchhoff Beam Equation with Variable Exponent and Time Delay
This paper is concerned with a stability result for a Kirchhoff beam equation with variable exponents and time delay. The exponential and polynomial stability decay are proved based on Komornik's inequality.

Fourier restriction to polynomial curves I: a geometric inequality [PDF]
We prove a Fourier restriction result for general polynomial curves in Rd. Measuring the Fourier restriction with respect to the affine arclength measure of the curve, we obtain a universal estimate for the class of all polynomial curves of bounded ...

A Stability Result for a Swelling Porous System with Nonlinear Boundary Dampings
In this work, we consider a swelling porous system where the damping terms are on the boundary. We establish an explicit and general decay result, without imposing restrictive growth assumption near the origin on the damping terms.

Universal Lp improving for averages along polynomial curves in low dimensions [PDF]
We prove sharp Lp → Lq estimates for averaging operators along general polynomial curves in two and three dimensions. These operators are translation-invariant, given by convolution with the so-called affine arclength measure of the curve and we obtain ...

The present paper investigates the stability of a one-dimensional thermoelastic-Bresse system, where viscoelastic damping is acting on the vertical angle displacement and thermal dissipation governed by Maxwell–Cattaneo’s law is effective on the shear ...

Arbitrary decay for a von Karman system with memory
In this paper we study the von Karman plate model with long range memory. By using the assumptions on the relaxation function due to Tatar (J. Math. Phys. 52:013502, 2011), we show an arbitrary rate of decay, which is not necessarily of an exponential or

General decay synchronization of delayed BAM neural networks with reaction–diffusion terms
In this paper, general decay synchronization of delayed bidirectional associative memory neural networks with reaction–diffusion terms is studied. First, a useful lemma is introduced to determine the general decay synchronization of considered systems ...
