چکیده
|
In this study, we examine biorthogonal wavelets that are tailored to a specific discrete pseudo-differential equation of the form tσu = f, where tσ is an invertible discrete pseudo-differential operator defined on the lattice z n for every f ∈ ℓ ² (z n ). our focus is on computing galerkin approximations of the solution to this problem using an adaptive algorithm.
