... applications, say, to highways and railways. The analysis of the problem is thus of interest to many mechanical, civil engineers and, so on: a number of researchers have made their contributions to the problem. ... with respect to the metric ||· − · || ∞ , and hence, converges uniformly to a function v i ∈ C 0 (R). So by Lemma 10 below, u ∗ ∈ C 1 (R) and u  ∗ = v 1 , since...
