An approximate theoretical scheme is introduced to compute the velocity of the front and its diffusive wandering due to the presence of noise. The theoretical approach is based on a multiple scale analysis rather than on a small noise expansion and is confirmed with numerical simulations for a wide range of the noise intensity. We report on the possibility of noise sustained solutions with a continuum of possible velocities, in situations where only a single velocity is allowed without noise.7 p.application/pdfeng(c) The American Physical Society, 1998Teoria quànticaTeoria quàntica de campsRelativitat especial (Física)Dinàmica de fluidsQuantum theoryQuantum field theorySpecial relativity (Physics)Fluid dynamicsinfo:eu-repo/semantics/article142299info:eu-repo/semantics/openAccess
