摘要: In this talk, I will report some results on the entirely nodal solutions for the nonlinear Choquard equation. By introducing the Coxeter symmetries, we construct saddle solutions for this nonlocal equation. These saddle solutions illustrate the nonlocal feature of the Choquard equation and in contrast the local counterpart of fractional Schr\"odinger equation can not have such type solutions. Particularly, we prove that the fractional Choquard equation also admits such type nodal solutions.
