摘要: We are concerned with a class of important Schrödinger equations in mathematical physics with logarithmic nonlinearities, establishing the existence of positive peak solutions. The primary challenges in applying the Lyapunov-Schmidt reduction to logarithmic scalar equations arise from the non-smooth nature and sublinear growth of the logarithmic nonlinearity. Our approach is based on a novel inner-outer decomposition, distinguishing it from the traditional gluing techniques. Furthermore, by employing the local Pohozaev identity technique, we obtain non-degeneracy results for the multi-peak solutions.
