Abstract

In this paper we establish the existence and multiplicity of nontrivial solutions to the following problem \begin{align*} \begin{split} (-\Delta)^{\frac{1}{2}}u+u+(\ln|\cdot|*|u|^2)&=f(u)+\mu|u|^{-\gamma-1}u,~\text{in}~\mathbb{R}, \end{split} \end{align*} where μ>0\mu>0, ()(*) is the convolution operation between two functions, 0<γ<10<\gamma<1, ff is a function with a certain type of growth. We prove the existence of a nontrivial solution at a certain mountain pass level and another ground state solution when the nonlinearity ff is of exponential critical growth.
