Hi! My name is Yan Yau (not Yan).
My research interests include Algebraic Number Theory and Arithmetic Geometry. In particular I am currently studying and thinking about questions in Arithmetic Topology, which is the study of Number Theory motivated through the perspective of viewing a knot in a 3-manifold as being analogous to a prime in a number field.
I can be contacted through email at yanyau.cheng(at)ed.ac.uk.
