Are we working exclusively over an algebraically closed field?

Siddharth Mahendraker

You mentioned geom points are the closed points...

Ok thank you!

At the beginning in the definition of a stable curve did we write a condition on the genus one components (sorry if I missed it!)

Hulya Arguz

36:34

yes, I got confused in the previous page then

Hulya Arguz

36:44

it is ok

Hulya Arguz

36:46

thank you

I think this proof shows there are no continuous families of automorphisms

Hulya Arguz

01:23:54

but why finite?

Hulya Arguz

01:24:01

it could be Z

Hulya Arguz

01:24:03

for instance

Hulya Arguz

01:24:19

The proof does not show finite I think

Hulya Arguz

01:24:22

yes

Hulya Arguz

01:25:29

yes

Hulya Arguz

01:25:50

maybe it follows from the fact that Isom(...is quasi projective

Hulya Arguz

01:25:52

not sure

Lucien Hennecart

01:26:06

yes because then it is quasi-compact I think

Jae Hee Lee

01:27:00

The base scheme S is assumed to be proper?

Hulya Arguz

01:27:29

ok thanks...
