On the probability of nonexistence in binomial subsets [PDF]
The Annals of Probability, 2020 Given a hypergraph $ =( ,\mathcal{X})$ and a sequence $\mathbf{p} = (p_ )_{ \in }$ of values in $(0,1)$, let $ _{\mathbf{p}}$ be the random subset of $ $ obtained by keeping every vertex $ $ independently with probability $p_ $. We investigate the general question of deriving fine (asymptotic) estimates for the probability that $ _{\mathbf{p}

Nonexistence of Positive Solutions for Quasilinear Equations with Decaying Potentials
Mathematics, 2020 In this paper, we consider a quasilinear Schrödinger equation, which arises from the study of the superfluid film equation in plasma physics. Our main goal is to find the growth condition for nonlinear term and decaying condition for the potential ...

Nonexistence theorems for traversable wormholes
, 1999 Gauss-Bonnet formula is used to derive a new and simple theorem of nonexistence of vacuum static nonsingular lorentzian wormholes. We also derive simple proofs for the nonexistence of lorentzian wormhole solutions for some classes of static matter such ...

Electronic Journal of Qualitative Theory of Differential Equations, 2015 We obtain results on nonexistence of nontrivial nonnegative solutions for some elliptic and parabolic inequalities with functional parameters involving the $p(x)$-Laplacian operator. The proof is based on the test function method.

On the nonexistence of hypercommuting polynomials [PDF]
Proceedings of the American Mathematical Society, 1977 If f ( x 1 , … , x n ) f({x_1}, \ldots ,{x_n}) is not central for R, then the additive group generated by all specializations of f in R contains a noncentral Lie ideal of R.

A Time-Fractional Differential Inequality of Sobolev Type on an Annulus
Axioms, 2023 Several phenomena from natural sciences can be described by partial differential equations of Sobolev-type. On the other hand, it was shown that in many cases, the use of fractional derivatives provides a more realistic model than the use of standard ...

Nonexistence of self-similar singularities for the 3D incompressible Euler equations
, 2006 We prove that there exists no self-similar finite time blowing up solution to the 3D incompressible Euler equations. By similar method we also show nonexistence of self-similar blowing up solutions to the divergence-free transport equation in $\Bbb R^n$.
