Abstract: A multiresolution approximation of is of multiplicity if there are *r* functions whose translates form a Riesz basis for . In the general theory we derive necessary and sufficient conditions for the translates of to form a Riesz basis for . The resulting reconstruction and decomposition sequences lead to the construction of dual bases for and its orthogonal complement in . The general theory is applied in the construction of spline wavelets with multiple knots. Algorithms for the construction of these wavelets for some special cases are given.
