In this paper,we study normalized solutions of the Chern-Simons-Schrödinger system with general nonlinearity and a potential in H^(1)(ℝ^(2)).When the nonlinearity satisfies some general 3-superlinear conditions,we obtain the existence of ground state normalized solutions by using the minimax procedure proposed by Jeanjean in[L.Jeanjean,Existence of solutions with prescribed norm for semilinear elliptic equations,Nonlinear Anal.(1997)]. 展开更多

该文主要研究R^(2)上一类Chern-Simons-SchrOdinger(CSS)方程在给定L^(2)范数下解的存在性.这类问题可转化为该方程对应能量泛函E_(p)^(β)(u)在约束条件‖u‖L^(2)(R^(2))=1下的变分求极小问题.对于质量次临界的情形,即p∈(0,2),该文... 该文主要研究R^(2)上一类Chern-Simons-SchrOdinger(CSS)方程在给定L^(2)范数下解的存在性.这类问题可转化为该方程对应能量泛函E_(p)^(β)(u)在约束条件‖u‖L^(2)(R^(2))=1下的变分求极小问题.对于质量次临界的情形,即p∈(0,2),该文应用简洁的方法证明了无论位势函数V(x)是否为0,这类约束变分极小化问题都是可达的;对于质量临界的情形,即p=2,该文找到了两个可显式给出的正常数β^(*)>β_(*),使得V((x)≡0时的约束变分极小化问题对于β>β_(*)或β∈(0,β_(*)]均不可达,而对于V(x)≠0时的约束变分极小化问题则在β∈(0,β_(*)]可达,β>β_(*)不可达.此外,该文还讨论了质量次临界的约束极小能量在p→2时的极限行为. 展开更多

This paper is concerned with the following Chern-Simons-Schrodinger equation -Δu+V(|x|)u+(∫_(|x|)^(∞)h(s)/su^(2)(s)ds+h^(2)(|x|)/|x|^(2))u=a(|x|)f(u)in R^(2),where h(s)=∫_(0)^(s)l/2u^(2)(l)dl,V,a:R^(+)→R are radially symmetric potentials and the nonlinearity f:R→R is of subcritical or critical exponential growth in the sense of Trudinger-Moser.We give some new sufficient conditions on f to obtain the existence of nontrivial solutions or ground state solutions.In particular,some new estimates and techniques are used to overcome the difficulty arising from the critical growth of Trudinger-Moser type. 展开更多
