The differential equation for forced resonance is solved by a distribution named for this man and Lorentz. For complete metric spaces, all sequences named for him are convergent, and he names a set of differential equations of the form x-squared times y-double prime, plus x times y-prime, plus y with Leonard Euler. More famous is a result he names with a German stating that the dot product of two vectors must be less than or equal to the product

For 10 points, name this French mathematician, who names that inequality with Schwarz.
