Fredholm, Erik Ivar (1866–1927)
Swedish mathematician who founded the modern theory of integral
equations. This became a major research topic in the first quarter of
the 20th century and underpinned important theoretical developments in physics;
David Hilbert, in particular, extended Fredholm's
work to arrive at the concept of Hilbert
space. Fredholm also devoted time to actuarial science and made a particularly
important contribution by proposing an elegant formula to determine the
surrender value of a life insurance policy. He earned his Ph.D. from the
University of Uppsala but then spent the rest of his academic career at
the University of Stockholm. Related category
