- Аннотация: There is currently growing interest in theoretical and experimental studies of topological superconductors. One of the well-known examples is Sr2RuO4, which is thought to be a chiral triplet p-wave superconductor [1-2]. There are several features of triplet p-wave superconductivity, among them the key signature is appearence of the odd-frequency states in the vicinity of surface, leading to formation undergap bound states. We theoretically study the properties of the surface states in a chiral p-wave superconductor. We use the quasiclassical Eilenberger formalism in the Ricatti parametrization to describe various types of the superconductor surface, including arbitrary roughness and metallic behaviour of the surface layer. Self-consistent solution of the problem provides spatial distribution of pair potential, density of states, spontaneous currents and surface impedance [3-5]. These results may provide important information on the underlying pairing symmetry in the bulk and clarify physics of the processes on the surface. [1] Y. Maeno, H. Hashimoto, K. Yoshida, S.
