Uniqueness of Maximal Curve Systems on Punctured Projective Planes
Xiao Chen, Wujie Shen
We show that the maximal -system of loops in a punctured projective plane is unique up to the mapping class group action if and only if the number of punctures is at most five.

Systems of curves on non-orientable surfaces
Xiao Chen
We show that the order of the cardinality of maximal complete -systems of loops on non-orientable surfaces is . In particular, we determine the exact cardinality…
