We consider the two-dimensional quasilinear wave equations with standard null-form type quadratic nonlinearities. We introduce a new streamlined framework and prove global wellposedness without using the Lorentz boost vector fields.

没有洛伦兹的二维拟线性波的全局适定性

我们考虑具有标准零型二次非线性的二维拟线性波动方程。我们引入了一个新的流线型框架,并在不使用洛伦兹提升向量场的情况下证明了全局适定性。
