Proceedings of the American Mathematical Society, Vol. 140, No. 11 (NOVEMBER 2012), pp. 3749-3760 (12 pages) In this paper, we will give a recursion formula for double Hurwitz numbers by the cut-join ...

Some strange mathematical sequences are always whole numbers — until they’re not. The puzzling patterns have revealed ties to graph theory and prime numbers, awing mathematicians. Simple, yes, but ...

Rubin's model for causal inference in experiments and observational studies is enlarged to analyze the problem of "causes causing causes" and is compared to path analysis and recursive structural ...

In this issue of The Journal of Credit Risk we present two research papers and two technical reports. The first research paper is "Recursive formulas for the default probability distribution with ...
