報(bào)告題目:Some new results on the Chern-Simons-Schrodinger system
摘要:We introduce normalized solutions to the Chern-Simons-Schrodinger system, which is a gauge-covariant nonlinear Schrodinger system with a long-range electromagnetic field, arising in nonrelativistic quantum mechanics theory. The solutions correspond to critical points of the underlying energy functional subject to the L2-norm constraint. We also study dynamics of the Chern-Simons-Schrodinger system with combined power-type nonlinearities (joint with Tianxiang Gou, Jianyi Chen, Kui Li ).

2.報(bào) 告 人:姬超副教授,華東理工大學(xué)
報(bào)告題目:A monotone property of the ground state energy to the scalar field equation and applications
時(shí)間:10:00-11:00
報(bào)告摘要:In this talk, we will introduce a new monotone result to the ground state energy to the scalar field equation. As applications, we use this monotone property to show the existence and concentration behavior of positive ground state solutions and least energy sign-changing solutions for the singularly perturbed elliptic equation with the variable exponent. This is a joint work with professor Zhi-Qiang Wang and Dr. Yuanze Wu.
