Nonnegative multiplicative controllability for semilinear multidimensional reaction-diffusion equations

Giuseppe Floridia

In this paper we consider a multidimensional semilinear reaction-diffusion equation and we obtain at any arbitrary time an approximate controllability result between nonnegative st…

Inverse problems for first-order hyperbolic equations with time-dependent coefficients

Giuseppe Floridia, Hiroshi Takase

We prove global Lipschitz stability for inverse source and coefficient problems for first-order linear hyperbolic equations, the coefficients of which depend on both space and time…

Backward problems in time for fractional diffusion-wave equation

Giuseppe Floridia, Masahiro Yamamoto

In this article, for a time-fractional diffusion-wave equation $\pppa u(x,t) = -Au(x,t)$, with fractional order , we consider the backward problem in time: dete…

Observability inequalities for degenerate transport equations

Giuseppe Floridia, Hiroshi Takase

In this paper we prove an observability inequality for a degenerate transport equation. First we introduce a local in time Carleman estimate for the degenerate equation, then we ap…

Well-posedness for the backward problems in time for general time-fractional diffusion equation

Giuseppe Floridia, Zhiyuan Li, Masahiro Yamamoto

In this article, we consider a partial differential equation with Caputo time-derivative: where and satisfies the zero Dirichlet boundary con…
