Resumen
WE OBTAIN CONDITIONS FOR THE EXISTENCE OF AN ATTRACTOR IN THE SYSTEM OF EQUATIONS DESCRIBING A TACHYON WARM INFLATIONARY MODEL WITH BULK VISCOSITY TAKEN INTO ACCOUNT. WHEN THESE CONDITIONS ARE MET THE EVOLUTION APPROACHES SLOW-ROLL REGIME. WE PRESENT THE PRIMORDIAL POWER SPECTRUM FOR THE TACHYON FIELD BY CONSIDERING A DISSIPATION COEFFICIENT DEPENDING ON THE SCALAR FIELD AND TEMPERATURE.
