| Apr 24, 2019 at 15:02 | comment | added | Francesco Polizzi | It seems to me (but I should check better) that all examples given by Nakayama have non-trivial automorphisms. | |
| Apr 24, 2019 at 14:50 | comment | added | user138661 | among surfaces with no finite surjective morphisms that are not automorphisms, are there surfaces with no automorphisms (other than the identity)? Quick scan through the paper did not tell me the answer and I am bad at surfaces. | |
