Toric Multivariate Gaussian Models from Symmetries in a Tree

Emma Cardwell, Aida Maraj, Alvaro Ribot

Given a rooted tree $T$ on $n$ non-root leaves with colored and zeroed nodes, we construct a linear space $L_{T}$ of $n \times n$ symmetric matrices with constraints determined by the…

Class Number Formulas for Certain Biquadratic Fields

Elizabeth Athaide, Emma Cardwell, Christina Thompson

We consider the class numbers of imaginary quadratic extensions $F (- p)$ , for certain primes $p$ , of totally real quadratic fields $F$ which have class number one. Using semi…
