Non-topological condensates in self-dual Chern-Simons gauge theory

Takashi Suzuki, Futoshi Takahashi (2004)

Banach Center Publications

This note is concerned with the recent paper "Non-topological N-vortex condensates for the self-dual Chern-Simons theory" by M. Nolasco. Modifying her arguments and statements, we show that the existence of "non-topological" multi-vortex condensates follows when the number of prescribed vortex points is greater than or equal to 2.

Nontrivial Solutions of Quasilinear Equations In BV

Marzocchi, Marco (1996)

Serdica Mathematical Journal

The existence of a nontrivial critical point is proved for a functional containing an area-type term. Techniques of nonsmooth critical point theory are applied.

Nontrivial solutions to boundary value problems for semilinear Δ γ -differential equations

Duong Trong Luyen (2021)

Applications of Mathematics

In this article, we study the existence of nontrivial weak solutions for the following boundary value problem: - Δ γ u = f ( x , u ) in Ω , u = 0 on Ω , where Ω is a bounded domain with smooth boundary in N , Ω { x j = 0 } for some j , Δ γ is a subelliptic linear operator of the type Δ γ : = j = 1 N x j ( γ j 2 x j ) , x j : = x j , N 2 , where γ ( x ) = ( γ 1 ( x ) , γ 2 ( x ) , , γ N ( x ) ) satisfies certain homogeneity conditions and degenerates at the coordinate hyperplanes and the nonlinearity f ( x , ξ ) is of subcritical growth and does not satisfy the Ambrosetti-Rabinowitz (AR) condition.

Nonuniqueness for some linear oblique derivative problems for elliptic equations

Gary M. Lieberman (1999)

Commentationes Mathematicae Universitatis Carolinae

It is well-known that the “standard” oblique derivative problem, Δ u = 0 in Ω , u / ν - u = 0 on Ω ( ν is the unit inner normal) has a unique solution even when the boundary condition is not assumed to hold on the entire boundary. When the boundary condition is modified to satisfy an obliqueness condition, the behavior at a single boundary point can change the uniqueness result. We give two simple examples to demonstrate what can happen.
