Simultaneous orthogonalization of inner products in infinite-dimensional vector spaces. Linear and Multilinear Algebra, (2025). https://hdl.handle.net/10630/38168 10.1080/03081087.2024.2447524 For an arbitrary field K and a family of inner products in a K-vector space V of arbitrary dimension, we study necessary and sufficient conditions in order to have a basis which is orthogonal relative to all the inner products. If the family contains a nondegenerate element plus a compatibility condition, then under mild hypotheses the simultaneous orthogonalization can be achieved. So we investigate several constructions whose purpose is to add a nondegenerate element to a degenerate family and we study under what conditions the enlarged family is nondegenerate. eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Álgebra lineal Análisis numérico Simultaneous orthogonalization of inner products in infinite-dimensional vector spaces journal article
