Your Horn torus is very interesting also for the division by zero calculus viewpoint. We saw many phenomena that tangential lines and normal lines are the same one in many cases, for example, please look the attached one. Now please look your model at the point at (0,0,1/2)!!
For the horn torus, do you kindly introduce some analytical theory papers or articles? I would like to study them.
