On 2-surfaces in R⁴ and Rⁿ
Froehlich, Steffen
Original · EN
In this overview report we generalize Erhard Heinz' curvature estimate for minimal graphs in R³ to graphs in Rⁿ of prescribed mean curvature. Secondly, we analyse these problems in the frame of the outer differential geometry which leads us to the notions of normal torsion and normal curvature for immersions in R⁴.
