Abstract

We construct a rectifiable stationary 2-varifold in ℝ⁴ with non-conical, and hence non-unique, tangent varifold at a point. This answers a question of Simon (Lectures on geometric measure theory, p 243, 1983) and provides a new example for a related question of Allard (Ann Math (2) 95(3):417–491, 1972, p 460). There is also a (rectifiable) stationary 2-varifold in ℝ⁴ that has more than one conical tangent varifold at a point.
