Decay/growth rates for inhomogeneous heat equations with memory. The case of large dimensions
(American Institute of Mathematical Sciences, 2021-07)
We study the decay/growth rates in all Lp norms of solutions to an inhomogeneousnonlocal heat equation in RN involving a Caputo -time derivative and a power of the Laplacianwhen the dimension is large, N > 4. Rates depend ...
Explicit solutions for a non-classical heat conduction problem for a semi-infinite strip with a non-uniform heat source
(Springer, 2015-12)
A non-classical initial and boundary value problem for a non-homogeneous one-dimensional heat equation for a semi-infinite material with a zero temperature boundary condition is studied. It is not a standard heat conduction ...
A family of singular ordinary differential equations of the third order with an integral boundary condition
(Springer, 2018-12)
We establish in this paper the equivalence between a Volterra integral equation of the second kind and a singular ordinary differential equation of the third order with two initial conditions and an integral boundary ...
A Note on the Convergence to inicial data of Heat and Poisson Equations
(American Mathematical Society, 2012-03)
We characterize the weighted Lebesgue spaces, Lp(ℝn, v(x)dx), for which the solutions of the Heat and Poisson problems have limits a.e. when the time t tends to zero. © 2012 American Mathematical Society.
Large-time behavior for a fully nonlocal heat equation
(Springer, 2021-09)
We study the large-time behavior in all Lp norms and in different space-time scales of solutions to a nonlocal heat equation in ℝN involving a Caputo α-time derivative and a power of the Laplacian (−Δ)s, s ∈ (0,1), extending ...
Continuous time random walks and the Cauchy problem for the heat equation
(Springer, 2018-10)
We deal with anomalous diffusions induced by continuous time random walks - CTRW in ℝn. A particle moves in ℝn in such a way that the probability density function u(·, t) of finding it in region Ω of ℝn is given by ∫Ωu(x, ...
A heat equation with memory: large-time behavior
(Academic Press Inc Elsevier Science, 2021-06)
We study the large-time behavior in all Lp norms of solutions to a heat equation with a Caputo α-time derivative posed in RN (0 < α < 1). These are known as subdiffusion equations. The initial data are assumed to be ...
Non-classical Stefan problem with nonlinear thermal coefficients and a Robin boundary condition
(Pergamon-Elsevier Science Ltd, 2019-10)
A non-classical one dimensional Stefan problem with thermal coefficients temperature dependent and a Robin type condition at fixed face x=0 for a semi-infinite material is considered. The source function depends on the ...
On Besov regularity of temperatures
(Birkhauser Boston Inc, 2010-12)
We prove space-time parabolic Besov regularity in terms of integrability of Besov norms in the space variable for solutions of the heat equation on cylindrical regions based on Lipschitz domains.
