Blow-up results for a logarithmic pseudo-parabolic $p (.)$ -Laplacian type equation

Belhaoues Razik, Umberto Biccari, Abita Rahmoune

In this paper, we consider an initial-boundary value problem for the following mixed pseudo-parabolic $p (.)$ -Laplacian type equation with logarithmic nonlinearity: $$ u_t-Îu_t-\mb…

Boundary observation and control for fractional heat and wave equations

Umberto Biccari, Mahamadi Warma, Enrique Zuazua

We establish boundary observability and control for the fractional heat equation over arbitrary time horizons $T > 0$ , within the optimal range of fractional exponents $s \in (1/2,…
