Problem 92

Primary tabs

Among degree $n$ polynomial maps of $[0,1]$ to itself, are Axiom A open and dense. Do bad ones form a stratified set? ...



The next two are named again (91) and (92) on the following page (and are barely legible)

seems that the second Problem 91 is a multi-body mechanics problem?

a. 3 particles on $S^1$; how do you do it?

b. 2 particles on $T^2$ with different mass

and there is a parenthetical "(write Keane)"
