The PiFORUM is an annual conference aimed at women and underrepresented genders within mathematics and related disciplines. This year it will be hosted by the University of Leicester on 2nd - 3rd September.
The two days will include a mini-symposium on Equality, Diversity and Inclusion, a series of contributed talks, a poster competition, two workshops and,of course, plenty of social time to meet everyone in our community.

Gotzmann's persistence theorem for smooth projective toric varieties
Abstract
Gotzmann's regularity and persistence theorems provide tools which allow us to find explicit equations for the Hilbert scheme Hilb_P(P^n). A natural next step is to generalise these results to the multigraded Hilbert scheme Hilb_P(X) of a smooth projective toric variety X. In 2003 Maclagan and Smith generalise Gotzmann's regularity theorem to this case. We present new persistence type results for the product of two projective spaces, and time permitting discuss how these may be applied to a more general smooth projective toric variety.

Subleading structure of asymptotically-flat spacetimes
Abstract
In this talk I will explain how a dictionary between the Bondi-Sachs and the Newman-Penrose formalism can be used to organize the subleading data appearing in the metric for asymptotically-flat spacetimes. In particular, this can be used to show that the higher Bondi aspects can be traded for higher spin charges, and that the latter form a w_infinity algebra.
