摘要
In this paper, we consider the solution to the linear Korteweg-De Vries (KdV) equation, both homogeneous and forced, on the quadrant {x is an element of R+,t is an element of R+}$\lbrace x\in \mathbb {R}<^>+,t\in \mathbb {R}<^>+\rbrace$ via the unified transform method of Fokas and we provide a complete rigorous study of the integrals of the formula provided by the method, especially focusing on the explicit verification of the considered initial-boundary-value problems (IBVPs), with generic data, as well as on the uniform convergence of all its derivatives, as (x,t)$(x,t)$ approaches the boundary of the quadrant, and their rapid decay as x ->infinity$x\;\rightarrow \;\infty$.
