Forced waves
WebFeb 1, 2024 · In the following, we will establish the existence and uniqueness of forced waves connecting 0 and u ∗. 2.1. Existence Lemma 2.1 Assume c > 0. Let φ − ( ξ) = max { δ [ 1 − e − c d ( ξ − ξ 0)], 0 }, where δ > 0 is small enough, ξ 0 is large enough that will be determined later.

WebAbstract. This article presents the results of numerical simulations of three-dimensional waves on the surface of a rivulet flowing down a vertical plate. The Kapitza–Shkadov approach is used to describe the wave flow of the rivulet. Various characteristics of linear and nonlinear regular waves in the rivulet are obtained through numerical ... WebIn this section, we shall study the existence of forced waves of (1.2). First, we prove the following result. Proposition 2.1 For any positive solution of (1.3), . Proof That ϕ ( ∞) = 0 follows from the fact h ( z) < 0 for all z ≫ 1, by a contradiction argument (cf. [11] ).
