well, I consider 150 to be special because it divides into 21,600 exactly(!) 144 times. Or was it 3600 6 times. Or maybe it was 6*6*6*100! (a centibeast?) And what the hell is a harmonic reciprocal?
Wow, isn't earth special? </sarcasm> ... (There are 21,600 minutes in every circle)
shhhhh, don't give it away to the rubes!
This should clear things up a bit!!!
Harmonic Reciprocal Mean Curvature Surfaces which are theta-isothermic
What is "theta-isothermic"? As one can define isothermic just by viewing on the functions of the fundamental forms - the Hopf differential is real with respect to a proper conformal coordinate - we define a surface to be theta-isothermic if the imaginary part of the Hopf differential is constant (theta) with respect to a proper conformal coordinate. However, neither is theta an invariant of the surface nor is the constant of the imaginary part of the Hopf differential a geomertrical property that is really understood up to now.
On the other side - even this is very new and not yet understood - for these "generalization" of isothermic surfaces there exist an involution, that maps a theta-isothermic surface (up to a scaling of the ambiente space) into an isothermic surface in either S3 or H3 and vice versa.
Somehow, your screen nick inspires a vague sense of fear and loathing in me... never mind, I forgot what I was saying.
