Title: Richard Stanley's solution of Anand-Dumir-Gupta conjecture about
enumeration of magic squares
Abstract: In 1973 Richard Stanley solved several conjectures about magic
squares
proposed by Harsh Anand, V. C. Dumir and Hans Raj Gupta. In his "Green
Book"
Stanley used the theory of Cohen-Macaulay and Gorenstein rings to solve
these
conjectures. I will sketch his solution assuming only basic commutative
algebra.
