ZUPPA, Carlos. A Compact trace theorem for domains with external cusps. Rev. Unión Mat. Argent. [online]. 2009, vol.50, n.1, pp.23-29. ISSN 0041-6932.

This paper deals with the compact trace theorem in domains with external cusps. We show that if the power sharpness of the cusp is bellow a critical exponent, then the trace operator exists and it is compact.

Keywords : Cuspidal domains; Compact trace operator.
