Some math stuff

• Ideal points of character varieties, algebraic non-integral representations, and undetected closed essential surfaces in 3-manifolds. Link to pre-print of a paper published in the Proceedings of the AMS. Joint work with Alex Casella and Stephan Tillmann.

• Modules, fields of definition, and the Culler–Shalen norm. Link to pre-print of a paper submitted to Algebraic and Geometric Topology.

• Twist-knot intersections in the character variety of the Whitehead link. Project in progress with Tim Morris. Link to some computations in Sage.
