Published in 2019 at "Mediterranean Journal of Mathematics"

DOI: 10.1007/s00009-019-1309-y

Abstract: We consider initial value problems for abstract evolution equations with fractional time derivative. Concerning the Caputo derivative $$\mathbb {D}^\alpha u$$Dαu, we show that certain assumptions, which are known to be sufficient to get a unique… read more here.

Published in 2019 at "Journal of Optimization Theory and Applications"

DOI: 10.1007/s10957-018-1305-6

Abstract: In this paper, we consider a diffusion equation with fractional time derivative with nonsingular Mittag-Leffler kernel in Hilbert spaces. We first prove the existence and uniqueness of solution by means of a spectral argument. Then,… read more here.

Published in 2022 at "Materials"

DOI: 10.3390/ma15072432

Abstract: This article introduces magneto-thermoelastic exchanges in an unbounded medium with a spherical cavity. A refined multi-time-derivative dual-phase-lag thermoelasticity model is applied for this reason. The surface of the spherical hole is considered traction-free and under… read more here.
