“…aqu(tr, x)g u(t, x)qu(tr, x) , and established the existence and global continuation of rotating waves. In the last few decades, neutral equations have been investigated wildly, and a variety of themes have been touched, such as the existence and uniqueness, regularity and stability of solutions [1,4,9,11,14,16,28], periodic solutions [10,24], controllability [23], and so on. But, to the best of our knowledge, there are few works that treat the traveling wave solution of partial neutral functional equations [12,13,20].…”
