چکیده
In the present paper, we investigate blow-up dynamics for local solutions to semilinear generalized Tricomi equation with combined nonlinearity. As a result, enlarge region in comparison ones corresponding models either power nonlinearity or of derivative type. Our approach is based on an iteration argument establish lower bound estimates space average solutions. Finally, obtain upper lifespan as byproduct our argument.

متن کاملOn Existence and Nonexistence Global Solutions of Reaction-Diffusion Equations
We consider the initial value problem for the reaction-diffusion equation ut = ∆u + f(u). In this paper we show the existence and nonexistence of the global solutions in time. Especially, we extend the condition of the nonlinear terms to more general. We have the results of the existence and the nonexistence for the equation with the nonlinear term f satisfying lim infs→0 f(s)/sp > 0 and lim su...
متن کاملLocal and global nonexistence of solutions to semilinear evolution equations
For a fixed p and σ > −1, such that p > max{1, σ + 1}, one main concern of this paper is to find sufficient conditions for non solvability of ut = −(−∆) β 2 u− V (x)u+ th(x)u +W (x, t), posed in ST := R × (0, T ), where 0 < T < +∞, (−∆) β 2 with 0 < β ≤ 2 is the β/2 fractional power of the −∆, and W (x, t) = tw(x) ≥ 0. The potential V satisfies lim sup|x|→+∞ |V (x)||x| < +∞, for some positive a...
متن کاملNonexistence of global solutions of abstract wave equations with high energies
We consider an undamped second order in time evolution equation. For any positive value of the initial energy, we give sufficient conditions to conclude nonexistence of global solutions. The analysis is based on a differential inequality. The success of our result is based in a detailed analysis which is different from the ones commonly used to prove blow-up. Several examples are given improvin...
متن کاملNonexistence of Positive Solutions for Some Fully Nonlinear Elliptic Equations
denote the kth elementary symmetric function, and let Γk denote the connected component of {λ ∈ R : σk(λ) > 0} containing the positive cone {λ ∈ R : λ1 > 0, · · · , λn > 0}. It is well known that Γk = {λ ∈ R : σl(λ) > 0, 1 ≤ l ≤ k}. Let S denote the set of n× n real symmetric matrices. For any A ∈ S we denote by λ(A) the eigenvalues of A. Throughout this note we will assume that Γ ⊂ R is an ope...
