The first objective of this paper is to prove the existence and uniqueness of global solutions for
a Kirchhoff-type wave equation with
nonlinear dissipation of the form Kuⁿ + 𝑀(|𝐴¹/²𝑢|²)𝐴𝑢 + 𝑔(𝑢')=0 under suitable
assumptions on 𝐾, 𝐴, 𝑀(⋅), and 𝑔(⋅). Next, we under some growth conditions on the nonlinear...
