Non-radial finite time blow-up for the fourth-order nonlinear Schrödinger equations

چکیده
We revisit the finite time blow-up for fourth-order Schrödinger equation with focusing inhomogeneous nonlinearity −|x|−2|u|4nu. By exploiting localized virial estimates and spatial decay of nonlinearity, we prove non-radial solutions negative energy. Our result is first one dealing existence to equations.

The finite time blow - up for the Euler - Poisson equations
We prove the finite time blow-up for C1 solutions to the EulerPoisson equations in R, n ≥ 1, with/without background density for initial data satisfying suitable conditions. We also find a sufficient condition for the initial data such that C3 solution breaks down in finite time for the compressible Euler equations for polytropic gas flows.

متن کاملFinite Time Blow-up for the 3D Incompressible Euler Equations
We prove the finite time blow-up for solutions of the 3D incompressible Euler equations, which happens along the fluid particle trajectories starting from a set of points. This set is specified by the relation between the deformation tensor and the Hessian of pressure both coupled with the vorticity directions, associated with the initial data. As a corollary of this result we prove the finite ...
متن کاملBlow-Up Time for Nonlinear Heat Equations with Transcendental Nonlinearity
where x ∈ R, F is a given nonlinear function and u is unknown. Due to the mathematical and physical importance, existence and uniqueness theories of solutions of nonlinear heat equations have been extensively studied by many mathematicians and physicists, for example, 1–10 and references therein. Unlike other studies, we focus on the nonlinear heat equations with transcendental nonlinearities s...
متن کاملFinite-time Blow-up and Global Solutions for Some Nonlinear Parabolic Equations
For a class of semilinear parabolic equations, we prove both global existence and finite-time blow-up depending on the initial datum. The proofs involve tools from the potential-well theory, from the criticalpoint theory, and from classical comparison principles.

We consider the L 2-gradient ow associated with the Yang-Mills functional, the so-called Yang-Mills heat ow. In the setting of a trivial principal SO(n)-bundle over R n in dimension n greater than 4, we show blow-up in nite time for a class of SO(n)-equivariant initial connections.
