Existence of sign-changing solutions for a logarithmic weighted Kirchhoff problem in the whole of ${\mathbb{R}}^N$ with exponential growth non-linearity

In this work, we establish the existence of solutions that change sign at low energy for a non-local weighted Kirchhoff problem in the set ${\mathbb{R}}^N,N>2$. The non-linearity of the equation is assumed to have exponential growth in view of the logarithmic weighted Trudinger-Moser inequalities. To obtain the existence result, we apply the constrained minimisation in the Nehari set, the quantitative deformation lemma and results from degree theory.
