The wave estimates

WebThe wave on the string travels in the positive x -direction with a constant velocity v, and moves a distance vt in a time t. The wave function can now be defined by. y(x,t) = Asin(2π λ (x−vt)). y ( x, t) = A sin ( 2 π λ ( x − v t)). It is often convenient to rewrite this wave function in a more compact form. WebL1 estimate for the wave equation does not hold [20], and thus one cannot obtain Strichartz estimates by interpolation between this dispersive estimate and the energy estimate (see also the remark at the end of Subsection 3.1). 2. This paper is divided into four sections.
