Discrete Math Seminar: Nick Olson-Harris

A pair of skew shapes are said to be (skew) equivalent if they admit the same number of semistandard tableaux of any weight; i.e. if their associated skew Schur functions are equal. A complete characterization is known for ribbon shapes (those with no 2×2 square) but the general case is more complicated. I will give a brief survey of existing results in the area and discuss some recent work of my own.
