General decay for a viscoelastic wave equation with strong time-dependent delay
Boundary Value Problems, 2017 A viscoelastic wave equation with strong damping and strong time-dependent delay in the internal feedback is considered. Under the assumption | μ 2 | < 1 − d μ 1 $|\mu_{2}|

Dispersive and Strichartz estimates for hyperbolic equations with constant coefficients
, 2008 Dispersive and Strichartz estimates for solutions to general strictly hyperbolic partial differential equations with constant coefficients are considered. The global time decay estimates of $L^p-L^q$ norms of propagators are obtained, and it is shown how

Temporal decay bounds in generalized heat conduction
Journal of Mathematical Analysis and Applications, 2004 The authors consider the generalized Maxwell-Cattaneo model for heat conduction in \(\mathbb R^N\) \((N = 2, 3)\). By using a suitable change of variable for the temperature \(T\) and exploiting the multiplier method, they establish an exponential decay bounds for \(T\), as well as its first partial derivatives, in the \(L_2(\Omega)\) norm.

Theoretical and Computational Results of a Memory-Type Swelling Porous-Elastic System
Mathematical and Computational Applications, 2022 In this paper, we consider a memory-type swelling porous-elastic system. First, we use the multiplier method to prove explicit and general decay results to solutions of the system with sufficient regularities.

Optical angular momentum: Multipole transitions and photonics [PDF]
, 2010 The premise that multipolar decay should produce photons uniquely imprinted with a measurably corresponding angular momentum is shown in general to be untrue.

Fermionic decay of a massive scalar in the early Universe
, 2019 We derive a curved space generalization of a scalar to fermion decay rate with a Yukawa coupling in expanding Friedmann-Robertson-Walker universes. This is done using the full theory of quantum fields in curved spacetime and the added-up transition ...

Magnetic Field Decay in Neutron Stars. Analysis of General Relativistic Effects [PDF]
, 2000 An analysis of the role of general relativistic effects on the decay of neutron star's magnetic field is presented. At first, a generalized induction equation on an arbitrary static background geometry has been derived and, secondly, by a combination of ...

General decay synchronization of delayed BAM neural networks with reaction–diffusion terms
Advances in Difference Equations, 2020 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 ...
