Current Development in Theory and Applications of Wavelets

Abstract: In this paper,
under mild condition, we give the sufficient and necessary condition that is a scaling function of in view of supportof
Fourier transform for Furthermore,
suppose is
an orthonormal wavelet of and
the whole support of its Fouriertransform
is
Under
the weakest condition that each is
continuous for we
obtain results on the above whole support of which
are characterized by some equalities and inequalities. We have improved
completely Long’s results and generalized Zhang’s results.
