## 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] ).

Condition

(Biorthogonal scaling functions) A pair of scaling functions comes from dual GMRA, is compactly supported and

1. the associated wavelets satisfy for some :

2. the supports of satisfy the condition

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

According to the definition ( Dual wavelets ),

We introduce the notations , , , , , , , similarly to the section ( Adapting MRA to the interval [0,1] ): According to the condition ( Biorthogonal scaling functions )-2,

Condition

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

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

Definition

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

We proceed to construct biorthogonal bases for , for each .

Let We choose , , , to satisfy

We represent the relationships and as for some matrixes chosen to satisfy : so that

If then is a square matrix of the form with some square matrixes The LU decomposition may be applied separately to the matrixes : for some permutation matrixes , lower triangular matrixes and upper triangular matrixes . The choice delivers one possible solution.
