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.

A blow-up result for the semilinear Euler-Poisson-Darboux-Tricomi equation with critical power nonlinearity [PDF]

open access: yesJournal of Mathematical Analysis and Applications
In this paper, we prove a blow-up result for a generalized semilinear Euler-Poisson-Darboux equation with polynomially growing speed of propagation, when the power of the semilinear term is a shift of the Strauss' exponent for the classical semilinear ...

Nonlocal problem for partial differential equations of fractional order

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
A nonlocal problem is investigated for the partial differential equation (diffusion equation of fractional order) in a finite domain. The boundary condition contains a linear combination of generalized operators of fractional integro-differentiation used

A Blow-Up Result for a Generalized Tricomi Equation with Nonlinearity of Derivative Type [PDF]

open access: yes, 2021
In this note, we prove a blow-up result for a semilinear generalized Tricomi equation with nonlinear term of derivative type, i.e., for the equation Tlu=|∂tu|p, where Tl=∂t2-t2lΔ.
