Measures on Cameron's treelike classes and applications to tensor categories
Thanh Can, Thomas Rüd
Measures on Fraïssé classes are a key input in the Harman--Snowden (2022) construction of tensor categories. Treelike Fraïssé classes provide a particularly tractable source of…

A comparison problem for abelian surfaces and descent for symplectic orbital integrals
Thomas Rüd
To answer a question about the distribution of products of elliptic curves in isogeny classes of abelian surfaces defined over finite fields, we compute specific orbital integrals…

A Projective Twist on the Hasse Norm Theorem
Thomas Rüd, Alan Bu
A finite extension of global fields satisfies the Hasse norm principle if any nonzero element of has the property that it is a norm locally if and only if it is a norm gl…
