full_question: The stick-breaking process is a constructive algorithm used to generate samples from a stochastic process named after this mathematician. This mathematician also names a multivariate continuous probability distribution defined on a n-dimensional simplex, which is the conjugate prior of the multinomial distribution. In analytic number theory, the Riemann zeta function is a simple non-trivial example of his type of series, which are sums over n of a-sub-n over n to a complex power s. This mathematician also names the eta function, a simple example of one of his L-functions. In contrast to Neumann boundary conditions, boundary conditions named after this man specify a function's value on the boundary of its domain. For 10 points, name this man who codified, and sometimes names, the pigeonhole principle.
