Periodic solutions for a p-Laplacian-like NFDE system
نویسندگان
چکیده
We consider an n-dimensional p-Laplacian-like neutral functional differential equation (NFDE) in the form d dt fp1⁄2xðtÞ cðtÞx0ðt tÞ þ d dt rFðxðt tÞÞ þ bðtÞrGðxðt dðtÞÞÞ 1⁄4 eðtÞ; where c(t) and bðtÞ are sign-changeable. Using Mawhin’s continuation theorem, we establish some criteria to guarantee the existence of periodic solutions for the above system, which generalize and improve on the corresponding results in related literature. & 2011 The Franklin Institute.
