Scaling Limits of Random Series-Parallel Maps.
A finite graph embedded in the plane is called a series-parallel map if it can be constructed from a tree by iteratively subdividing and doubling edges. In this talk, we investigate the scaling limits of weighted random two-connected series-parallel maps with $n$ edges. Under suitable integrability conditions on the weights, we show that when distances are rescaled by a factor of $n^{-1/2}$, these maps converge in the Gromov–Hausdorff sense to a constant multiple of Aldous’ continuum random tree (CRT). The proof relies on a bijection between certain families of trees and series-parallel maps, allowing us to analyze geodesics using a Markov chain argument introduced by Curien, Haas, and Kortchemski (2015).

Homomorphisms and isomorphisms of real commutative Banach algebras into C(X).
We give conditions, either on the dual space of an algebra A or on the norm of the algebra, which garantee the existence of homomorphism or isomorphism into C(X).
