Adapting GMRA to interval [0,1].

e build on results of the section ( Calculation of biorthogonal wavelets ) and use technique of the section ( Adapting MRA to the interval [0,1] ).


(Biorthogonal scaling functions) A pair of scaling functions $\phi,\tilde{\phi}$ comes from dual GMRA, is compactly supported and

1. the associated wavelets $\psi,\tilde{\psi}$ satisfy MATH for some $N,\tilde{N}$ : MATH

2. the supports of $\phi,\tilde{\phi}$ satisfy the condition MATH

Therefore, according to the proposition ( Reproduction of polynomials 4 ), MATH

According to the definition ( Dual wavelets ), MATH

We introduce the notations $K_{d}$ , $K_{d,L}$ , $K_{d,R}$ , $K_{d,I}$ , $\tilde {K}_{d}$ , $\tilde{K}_{d,L}$ , $\tilde{K}_{d,R}$ , $\tilde{K}_{d,I}$ similarly to the section ( Adapting MRA to the interval [0,1] ): MATH MATH According to the condition ( Biorthogonal scaling functions )-2, MATH


(Sufficiently fine scale 2) We assume that the parameter $d$ is sufficiently large so that MATH

For a polynomial MATH we have MATH We introduce the notation MATH In particular, MATH


([0,1]-adapted GMRAs) We define the spaces MATH MATH

We proceed to construct biorthogonal bases for MATH , MATH for each $d$ .

Let MATH MATH We choose MATH , MATH , MATH , MATH to satisfy MATH

We represent the relationships MATH and MATH as MATH MATH for some matrixes $A,\tilde{A}$ chosen to satisfy MATH : MATH so that MATH

If $N=\tilde{N}$ then $X$ is a square matrix of the form MATH with some square matrixes $X_{1},X_{2}.$ The LU decomposition may be applied separately to the matrixes $X_{1},X_{2}$ : MATH for some permutation matrixes $P_{i}$ , lower triangular matrixes $L_{i}$ and upper triangular matrixes $U_{i}$ . The choice MATH delivers one possible solution.
