Tricomi problem and integral equations

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки
Formulas for inverting integral equations that arise when studying the Tricomi problem for the Lavrentyev–Bitsadze equation were derived. Solvability conditions of an auxiliary overdetermined problem in the elliptic part of the mixed domain were found ...

Existence of a principal eigenvalue for the Tricomi problem

open access: yesElectronic Journal of Differential Equations, 2000
The existence of a principal eigenvalue is established for the Tricomi problem in normal domains; that is, the existence of a positive eigenvalue of minimum modulus with an associated positive eigenfunction.

The conditional stability and an iterative regularization method for a fractional inverse elliptic problem of Tricomi-Gellerstedt-Keldysh type [PDF]

open access: yesMathematical Modelling and Analysis
The present paper is devoted to identifying an inaccessible boundary condition for a fractional elliptic problem of Tricomi-Gellerstedt-Keldysh-type. Using the expansion Fourier method, the considered problem can be reformulated as an operator equation ...

On the Tricomi problem [PDF]

open access: yes, 1986
The Tricomi equation is solved by the decomposition method[6–8] on the half-space x, y > 0 and also for suitable boundary conditions given on the Boundary of the hyperbolic-elliptic ...

Two generalized Tricomi equations [PDF]

open access: yes, 2021
In this note we give existence results for the generalized Tricomi equations Ru′ ′+ Bu= f and (Ru′)′+Bu=f with suitable boundary data where R may be an operator (or a function) depending also on time assuming positive, null and negative sign, while B is ...

Critical exponents for semilinear Tricomi-type equations [PDF]

open access: yes, 2016
In this thesis, we consider the semilinear Tricomi-type equations. In particular, we work on the global Cauchy problem for the semilinear Tricomi-type equation with suitable initial data.
