Gabai proved that homotopy hyperbolic 3-manifolds are virtually hyperbolic, in the paper of that name:
Gabai, David, Homotopy hyperbolic 3-manifolds are virtually
hyperbolic.
J. Amer. Math. Soc. 7 (1994), no. 1, 193–198.
I suspect this is the best you can do without geometrisation.
Leave $ φ_n $ Be a sequence of characteristic functions. We know that converge at each point of a not empty
open interval around 0 yet function $ φ which is also continued at 0.
Can you say that the sequence
of the distribution functions corresponding to $ φ_n $They are tight
I am aware of the test of a different version where convergence occurs in the entire real line. But what to do in this case?
I have seen this error NDSolve :: ndsz many times when I use NDSolve To obtain the solution of a non-autonomous ODE. I try but everything has failed. Thanks, Here is the code, very simple.
s = NDSolve[{x'
Y
X[0] == 1, and[0] == 1}, {x
