Boundary observation and control for fractional heat and wave equations
Umberto Biccari, Mahamadi Warma, Enrique Zuazua
We establish boundary null controllability of the heat equation driven by the integral fractional Laplacian on a bounded smooth domain for every and every fractional…
Computational performance of the MMOC in the inverse design of the Doswell frontogenesis equation
Alexandre Francisco, Umberto Biccari, Enrique Zuazua
Inverse design of transport equations can be addressed by using a gradient-adjoint methodology. In this methodology numerical schemes used for the adjoint resolution determine the…
Controllability and Positivity Constraints in Population Dynamics with age, size Structuring and Diffusion
Yacouba Simpore, Umberto Biccari
In this article, we consider the infinite dimensional linear control system describing the Population Models Structured by Age, Size, and Spatial Position. The control is localized…
Null Controllability for a Degenerate Structured Population Model
Yacouba Simporé, Yassine El gantouh, Umberto Biccari
In this paper, we consider the infinite dimensional linear control system describing population models structured by age, size, and spatial position. The diffusion coefficient is d…
Gaussian Beam ansatz for finite difference wave equations
Umberto Biccari, Enrique Zuazua
This work is concerned with the construction of Gaussian Beam (GB) solutions for the numerical approximation of wave equations, semi-discretized in space by finite difference schem…
A two-stage numerical approach for the sparse initial source identification of a diffusion-advection equation
Umberto Biccari, Yongcun Song, Xiaoming Yuan +1
We consider the problem of identifying a sparse initial source condition to achieve a given state distribution of a diffusion-advection partial differential equation after a given…
