This paper takes (4+1)-dimensional Fokas equation as an example to introduce an ingenious limit approach to generate degenerate solutions in detail. Under this technique. we start with solutions describing lump chains and obtain degenerate solutions from coupled lump chains quickly and easily. The complex dynamics of these degenerate solutions are shown in both three-dimensional plots... https://parisnaturalfoodes.shop/product-category/vitamin-c-complex/
