The dynamics of relativistically strong electromagnetic (EM) wave propagation in a hot electron-positron plasma is investigated. The possibility of finding localized stationary structures of EM waves is explored. It is shown that under certain conditions an EM wave forms a stable localized solitonlike structure where plasma is completely expelled from the region of the EM field location.
