It is nice to know that you will present your result at the Tokyo Institute of Technology. Please remember to mention Isabelle/HOL, which is a software in which x/0 = 0. This software is the result of many years of research and a millions of dollars were invested in it. If x/0 = 0 was false, all these money was for nothing. Right now, there is a team of mathematicians formalizing all the mathematics in Isabelle/HOL, where x/0 = 0 for all x, so this mathematical relation is the future of mathematics. https://www.cl.cam.ac.uk/~lp15/Grants/Alexandria/
There are millions of dollars invested in Isabelle/HOL, where x/0 = 0 (this is not a joke): https://www.cl.cam.ac.uk/~lp15/Grants/Alexandria/ Prof. Saitoh derived that x/0 = 0 from pure geometric intuition and he was right.
2019.3.8.22:23: The deduction that z/0 = 0, for any z, is based in Saitoh's geometric intuition and it is currently applied in proof assistant technology, which are useful in industry and in the military.
