A modification of the hierarchical basis finite element method is proposed and analyzed by using the wavelet method, see Jaffard [1]. The new basis has local support and results in uniform condition number when applied to discretize partial differential equations. Applications to second order elliptic equations (symmetric or non-symmetric) and Stokes equations (standard or stablized finite elements) are discussed.
