Abstract

‎In this paper we focus on the Cauchy problem for the generalized‎ ‎IBq equation with damped term in $n$-dimensional space‎. ‎We establish the global existence and decay estimates of solution with $L^q(1\leq q\leq 2)$ initial value‎, ‎provided that the initial value is suitably small‎. ‎Moreover‎, ‎we also show that the solution is asymptotic to the solution $u_L$ to the corresponding linear equation as time tends to infinity‎. ‎Finally‎, ‎asymptotic profile of the solution $u_L$ to the linearized problem is also discussed‎.
