“…Next we apply some of the ideas in [8,9] showing that the average of tan ϕ (or any f (ϕ) where f is increasing) on the interval [−n, n] is a monotonic function of p. Thus, for each fixed α, there is a unique p, such that this average is exactly tan α. We denote this solution (with α fixed) by (c n , ϕ n ).…”

“…This question is related to the passage to the limit in (62) as λ ↓ 0. By the result of [6], it is known that some sequence converges towards a viscosity solution of the Hamilton-Jacobi equation −c + A(z) e −E(z) b g 1 + w 2 z = 0 (with c = c 0 (λ = 0)). Unfortunately, the convergence of the whole family is not clear because this solution is not unique (even up to the addition of a constant).…”

“…Let us continue with some general comments on the literature. Models of similar type are considered in [3,6,12,7,10] but with slightly different assumptions. In [3], the striations are vertical and the front's profile is a straight line.…”

“…In [2], which deals with vertical striations (R(x,y) = R(x),1-periodic), it is shown that there exists a unique 'horizontal' line-shaped traveling front (c, φ), φ being 1-periodic and c the speed of the wave in the y direction. The latter traveling front corresponds therefore to the undulated version of the horizontal line in the case of a constant R.…”
