Fourier TransformEncyclopedia of Thermal Stresses
No full textThe Fourier transform is a key tool in several research fields: engineering, mathematics, applied mathematics, and physical science. We approach to this instrument assuming that the mathematical background of the readers might be various. Hence, the subject has been developed progressively. In particular in the first vintroductory part, the main relationship with the Fourier series has been put in evidence. Successively a rigorous mathematical discussion permits to deal with the subject in different functional spaces even arriving to the distributional framework. Some examples and applications are vintroduced and developed in the detail. In order to give the larger spectrum concerning the Fourier transform applications, even some topics like the discrete Fourier transform and the Shannon theorem are discussed

On two phase free boundary problems governed by elliptic equations with distributed sources
Full text linkWe present some recent progress on the analysis of two-phase free boundary problems governed by elliptic operators, with non-zero right hand side. We also discuss on several open questions, object of future investigations
Two-phase problems with distributed sources: regularity of the free boundary
Full text linkWe investigate the regularity of the free boundary for a general class of two-phase free boundary problems with nonzero right-hand side. We prove that Lipschitz or flat free boundaries are C1,γ. In particular, viscosity solutions are indeed classical
