Title	Binomial coefficients, exterior products, symmetric polynomials, and lambda rings in orbifold geometry
Abstract	I will talk about connections between binomial coefficients, exterior products, symmetric polynomials, and power sums. Although some of these ideas and relations predate Newton, they provide tools that are surprisingly useful for studying “modern” objects, including manifolds or varieties with group actions (orbifolds), representation theory, and resolutions of singularities.
