Critical curve for weakly coupled system of semilinear Euler-Poisson-Darboux-Tricomi equations
Yuequn Li, Fei Guo
This paper investigates a weakly coupled system of semilinear Euler-Poisson-Darboux-Tricomi equations (EPDTS) with power-type nonlinear terms. More precisely, in the case where the…

Lifespan estimate for the semilinear regular Euler-Poisson-Darboux-Tricomi equation
Yuequn Li, Fei Guo
In this paper, we begin by establishing local well-posedness for the semilinear regular Euler-Poisson-Darboux-Tricomi equation. Subsequently, we derive a lifespan estimate with the…
