Rectifiable Set

The rectifiable sets include the image of any Lipschitz Function from planar domains into . Thefull set is obtained by allowing arbitrary measurable subsets of countable unions of such images of Lipschitzfunctions as long as the total Area remains finite. Rectifiable sets have an ``approximate'' tangent plane at almost every point.
