The decreasing rate of the nonstationary conjuagate quadrature filters
by
Li Qi
Department of Mathematics, NUS
Coauthors: Tang Wai Shing

In the paper, we study the convergent rate of the coefficients of the polynomials

solutions qk of the equations


pk(x) qk(1-x)+ pk(1-x)qk(x) = 1, k in \N,

and the convergent rate of the nonstationary conjugate quadrature filters.

Our main tool is the divided difference and the Riesz factorization.
