Funds of Funds: A Closer Look at Age-Based Investing [PDF]

open access: yes, 2007
Over the next 20 years, 76 million Americans born between 1946 and 1964 will hit the half-century mark. For most, this means facing up to the hard questions of how, or even if, they will be able to afford retirement.

The rational function analogue of a question of Schur and exceptionality of permutation representations

open access: yes, 2002
In 1923 Schur considered the following problem. Let f(X) be a polynomial with integer coefficients that induces a bijection on the residue fields Z/pZ for infinitely many primes p.
