Abstract A mixed problem for the modified KdV equation in Q = (0,1) × (0,∞)$$u_t + b(t)uu_{x}+ a(t)u_{xxx}+ d(t)u= f(x,t) $$where a ( t )>0, is considered. No restriction on the sign of d ( t ) is imposed. We prove the existence and uniqueness of strong and weak global solutions as well as the exponential decay of solutions as t →+∞.
