As somebody used to say:
Does research. Smokes. Battles administration. Smokes. Wishes he could stop battling administration so that he could have more time to do research. Smokes some more.
The same. Except I do not smoke.

for which values of $\theta$ does this equation $x_{n+1}=\cos(\theta)x^2_{n}-\sin(\theta)x^2_{n-1}$ have bounded solutions?
Every ball centered at $0$ with radius at most $1/(|A|+|B|)$ is stable by the dynamics. For every $\theta$, $1/(|A(\theta)|+|B(\theta)|)\leqslant1/\sqrt2$. For every starting point such that $x_{-1}^2+x_0^2\lt1/2$, $x_n\to0$ at least geometrically fast. |

Brownian local time density
@lost1 No, the local time at 0 does not say anything about the distribution of the time spent above 0. Is this your question? (And no I had not seen the MSE question, whose answer is entirely standard.) |

Is minimum of convex envelope the same as minimum of the original function?
@CristóbalGuzmán Nice to see the nonconvexity of $f$ is not a problem anymore. The modification you now suggest is trivial--I am sure you will figure it with pleasure. |

@CristóbalGuzmán Off-topic. Please refer to my comment dated Nov 15 '12 at 12:19 on Yiyong Feng's post. |
