本文研究二维空间中不可压缩的无限深水波方程,其中有重力和常涡量,但没有表面张力。我们认为这个问题表示在位置-速度潜在的全纯坐标,并证明大数据的局部适定性,以及小数据的解决方案的立方寿命界。
This article is concerned with the incompressible, infinite depth water wave equation in two space dimensions, with gravity and constant vorticity but with no surface tension. We consider this problem expressed in position-velocity potential holomorphic coordinates, and prove local well-posedness for large data, as well as cubic lifespan bounds for small data solutions.
