We study the existence and uniqueness of smooth mean curvature flow, in arbitrary dimension and co-dimension, emanating from so called k-dimensional $$(\varepsilon ,R)$$(ε,R) Reifenberg flat sets in $$\mathbb {R}^n$$Rn. The Reifenberg condition, roughly speaking, says that the set has a weak metric notion of a k-dimensional tangent plane at every point and scale, but those tangents are allowed to tilt as the scales vary. We show that if the Reifenberg parameter $$\varepsilon$$ε is small enough… CONTINUE READING
