Regularity and upper semicontinuity of pullback attractors for a class of nonautonomous thermoelastic plate systems (Q2305347)

The authors study the small vibrations of a homogeneous, elastic and thermal isotropic Euler-Bernoulli plate. This mathematical model is described by a semilinear nonautonomous system of equations. For this problem, the authors prove the local and global posedness and the existence, uniform boundedness, regularity and upper semicontinuity with respect to a functional parameter of pullback attractors by using the theory of uniform sectorial operators.
