제     목 : Total curvature of Knots
내     용 :
The total curvature is a quantity which measures the total turning of tangent vector. John Milnor proved that it is a invariant of knot in the Euclidean space. Total curvature is related to stick number and lattice length of one dimensional knot. In this talk, I introduce Milnor’s result.
