“…Recently, Tahamtani and Shahrouzi studied asymptotic behavior of solutions for the following inverse problem: and showed that the solutions of this problem under some appropriate conditions are stable if α 1 and α 2 being large enough, α 3 ≥0 and ϕ ( t ) tend to zero as time goes to infinity and established a blow‐up result, if α 3 <0 and ϕ ( t ) = k be a constant. For more information about inverse problems, we refer the readers to the works in .…”
