Two limit cycles which lie on the same leaf

Possibly a very "brute force" approach could be the following. Take an non-singular algebraic curve $H(x,y)=0$ given by a polynomial $H(x,y)$ with real coefficients that has at least two ovals in the …

The type of a Riemann surface arising from a polynomial vector field

Well, in general not too much can be said without further information. For sure the leaf has a nontrivial fundamental group, so not an elliptic Reiamann surface (i.e. a Riemann sphere). But it could …

Question on Weil-Petersson metric on Teichmuller space

One way to define Teichmueller space is to fix a Riemann surface $X$, with a fixed complex structure, and define the space of all Beltrami differentials $\mathcal{M}(X)$ on $X$. Notice that in this wa …
