## Abstract If __X__ is a locally compact Polish space, then LSC(__X__, โ„) denotes the compact Polish space of lower semiโ€continuous realโ€valued functions on __X__ equipped with the topology of epiโ€convergence. Our purpose in this article is to prove the following: if โ€“โˆž < __ฮฑ__ < __ฮฒ__ < โˆž and โ€“โˆž
