Abstract
We give an alternative proof of Alinhac's almost global existence result for the Cauchy problem of quasilinear wave equations with quadratic nonlinearity satisfying the null condition in 2-D (S. Alinhac, 2001, [3]). The main innovation of our proof is that the Lorentz boost operator is not employed in the generalized energy estimates.
