Gaussian
charge optimisation confirms ridge scaling
¥Stretching energy can be expressed as an integral of
gaussian curvature analogous to electrostatic energy.
¥A stretching ridge has negative gaussian
curvature.
¥It must be compensated by an equal amount of
positive gaussian curvature on the adjacent flanks
¥Optimising the width w of this ÒchargeÓ
distribution gives
¥w ~ X (X/h)-1/3 , confirming other methods.
