Universal moduli spaces of Riemann surfaces

Lizhen Ji, Jürgen Jost
2017 Journal of Geometry and Physics  
The construction starts with a universal moduli space of Abelian varieties. This space carries a structure of an infinite dimensional locally symmetric space which is of interest in its own right.  ...  Applications to the Plateau-Douglas problem for minimal surfaces of varying genus and to the partition function of Bosonic string theory are outlined.  ...  Acknowledgments: We would like to thank K.-H. Neeb for helpful conversations on infinite dimensional symmetric spaces and for pointing out several references.  ...

As an example, in the basic theory of symmetric spaces one finds that the R-rank of G equals the dimension of a maximal flat totally geodesic submanifold in X. Such manifolds are called R-flats.  ...  The first conjecture suggests that Gromov limits of certain stratified sets are themselves stratified.  ...
