AB - In the framework of an explicitly correlated formulation of the electronic Schrödinger
equation known as the transcorrelated method, this work addresses some fundamental issues
concerning the feasibility of eigenfunction approximation by hyperbolic wavelet bases.
Focusing on the two-electron case, the integrability of mixed weak derivatives of
eigenfunctions of the modified problem and the improvement compared to the standard
