| Abstract: |
| In this paper, we study the problem of the strong edge-coloring of Möbius ladder C(2n,n). By using the combinatorial method, we obtain the following results: χ's(C(2n,n))=9 if n=3; χ's(C(2n,n))=10 if n=4; χ's(C(2n,n))=8 if n=5,8; χ's(C(2n,n))=6 if n>3 and n≡2(mod 4); χ's(C(2n,n))=7 if n>7 and n≡0,1 or 3 (mod 4). |
