講座內(nèi)容:
In this talk we will discuss the bounded solutions of the 1-D Q-curvature equation
(1)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ {\frac{1}{9}u}^\frac{5}{3}(u^{iv}+10u''+9u)=1.
A solution u of (1) defined on R is called bounded if there exists C>0 such that
1/C\le u(x)\le C\ x\in\mathbb{R}.
In particular, periodic and quasi-periodic solutions are bounded. We will classify all bounded solutions of (1) and discuss some of its consequences.
