“…In this article, under certain assumptions on g(s), V (x), f (x, s), and h(x), and by applying a fixed point theorem (see Lemma 2.6), as in [22] we show that (1.1) admits at least one weak solution. Here, the potential V (x) has similar characteristics as in [22]. The nonlinear term f (x, s) can be discontinuous and the critical exponential growth is allowed for it.…”
