  ABSTRACT: In this article, we study a generalized nonlinear Schrödinger equation with second- and fourth-order diffraction, a weak nonlocality, and cubic and quintic nonlinearities. We show that this equation possesses several exact analytical solutions. In particular, it has embedded and standard bright solitons, kinks, and standard and asymmetric dark solitons. The Vakhitov-Kolokolov stability criterion shows that the embedded solitons may be VK-stable or VK-unstable, the standard solitons are VK-unstable, and the dark solitons are VK-stable. It is shown that if the embedded solitons are perturbed, they emit monochromatic radiation.
