Hi, I want to typeset a graph comprising of one vertex (\bullet) and two
edges from the vertex to itself.
I want that the first edge begins and ends at (ur,dr) and that the second
begins and ends at (u,d), and that the two edges be to the right of the
\bullet without intersecting each other.
For the first edge, no problem, but I don't know how to type the second.
I tried things like :
\bullet \ar@(ur,dr) \ar@(u,d)@/^/}
the first edge works, but not the second.
Could you help me?
(english is not my native language, sorry for the mistakes)
