Resumo(s)
The closest point of a linear variety to an external point is found by
using the equality case of an Ostrowski’s type inequality. This point is
given in a closed form as the quotient of a formal and a scalar Gram
determinant. Then the best approximation pair of points onto two
linear varieties is obtained, besides its characterization.
