For ten points, identify this French mathematician, whose namesake sequences all converge in the real numbers.
A theorem named for this mathematician states that polyhedra with con- gruent corresponding faces are congruent. An equation named for this mathe- matician has a set of solutions which was found by Georg Hamel, and describes   additive functions. This mathematician names a quantity that is the con- volution of two power series -- his  product . The theorem stating that the contour integral of a complex-valued holomorphic function is zero is called this mathematician's integral theorem. This mathematician, with Schwartz, names an inequality relating to inner products. For ten points, identify this French mathematician, whose namesake sequences all converge in the real numbers.
