| contents | In this article, we study certain transcendental function spaces arising in potential theory within the framework of Orlicz spaces. Specifically, we generalize Bessel and Lizorkin-Triebel spaces to the nonstandard setting of Orlicz spaces. We recover classical results from potential theory, such as the fact that Bessel-Orlicz spaces of integer order coincide with Orlicz-Sobolev spaces (Calderón type theorem), and we establish inclusion results for fractional orders. Moreover, we prove a Strauss-type lemma for potential spaces. In the last sections, we show that certain Orlicz-Lizorkin-Triebel spaces coincide with Bessel-Orlicz spaces, and we provide a useful atomic decomposition for these spaces. |
