Nov 15, 2019 at 22:06 | comment | added | MyCindy2012 | @GerryMyerson: Thanks for your suggestion. I read some references and it seems beyond my grasp right now. I think to this question, some counterexamples are pointed out. The function I actually encountered is described here math.stackexchange.com/questions/3434922/… | |
Nov 15, 2019 at 11:54 | comment | added | Gerry Myerson | So, have you had a look at any Morse Theory reference? | |

Nov 14, 2019 at 0:40 | comment | added | Gerry Myerson | I think this can be answered using Morse Theory but you'll have to find an intro-level exposition to see the application. en.wikipedia.org/wiki/Morse_theory | |
