Superlinear Lower Bounds Based on ETH [PDF]
, 2022 We introduce techniques for proving superlinear conditional lower bounds for polynomial time problems. In particular, we show that CircuitSAT for circuits with m gates and log(m) inputs (denoted by log-CircuitSAT) is not decidable in essentially-linear ...

Electronic Journal of Qualitative Theory of Differential EquationsWe are concerned with the radial solutions of the Dirichlet problem $-\Delta u=K(|x|)f(u)$ on the exterior of the ball of radius $R>0$ centered at the origin in $\mathbb{R}^N \text{ with } N\geq 3$ where $f$ is superlinear at $\infty$ and has a ...

On a superlinear periodic boundary value problem with vanishing Green's function
Electronic Journal of Qualitative Theory of Differential Equations, 2016 We prove the existence of positive solutions for the boundary value problem \[ \begin{cases} y^{\prime \prime }+a(t)y=\lambda g(t)f(y),\quad 0\leq t\leq 2\pi, \\ y(0)=y(2\pi ),\quad y^{\prime }(0)=y^{\prime }(2\pi ), \end{cases} \] where $\lambda $ is ...

Nontrivial solutions for Klein–Gordon–Maxwell systems with sign-changing potentials
Boundary Value Problems, 2022 This paper is concerned with the nonlinear Klein–Gordon–Maxwell systems. Unlike all known results in the literature, the Schrödinger operator − Δ + V $-\Delta +V$ is allowed to be indefinite and the weaker superlinear conditions are imposed instead of ...

Superlinear elliptic hemivariational inequalities
Hacettepe Journal of Mathematics and Statistics, 2023 We study a nonlinear nonhomogeneous Dirichlet problem with a nonsmooth potential which is superlinear but without satisfying the Ambrosetti-Rabinowitz condition. Using the nonsmooth critical point theory and critical groups we prove two multiplicity theorems producing three and five solutions respectively. In the second multiplicity theorem, we provide

Multiple solutions to elliptic equations on $\mathbb{R}^N$ with combined nonlinearities
Electronic Journal of Qualitative Theory of Differential Equations, 2015 In this paper, we are concerned with the multiplicity of nontrivial radial solutions for the following elliptic equation \begin{equation*} \begin{cases} - \Delta u +V(x)u = -\lambda Q(x)|u|^{q-2}u+ Q(x)f(u),\quad x\in\mathbb{R}^N,\\ u(x)\rightarrow ...

Existence of solutions for the Dirichlet problem with superlinear nonlinearities [PDF]
, 1997 summary:In this paper we establish the existence of nontrivial solutions to \[\frac{\mathrm d}{{\mathrm d}t}L_{x^{\prime }}(t,x^{\prime }(t))+V_{x} (t,x(t))=0,\quad x(0)=0=x(T),\] with $V_x$ superlinear in $x$

Hedging, arbitrage and optimality with superlinear frictions [PDF]
The Annals of Applied Probability, 2013 In a continuous-time model with multiple assets described by càdlàg processes, this paper characterizes superhedging prices, absence of arbitrage, and utility maximizing strategies, under general frictions that make execution prices arbitrarily unfavorable for high trading intensity.
