WebMar 31, 2014 · In [Sal14], the author established the following theorem which shows a certain rigidity among a particular class of surface bundles over surfaces. Let Mod g … Web$\begingroup$ It's not that easy to visualize maps between surfaces of genus 2 or more. One way of generating examples is to look at congruence subgroups in arithmetic groups in SL(2,R) but basically it's a world very different from tori. $\endgroup$ distance from elkhart in to shipshewana in
