In this post, we simplily discuss the basic notions of profinite groups.
In this post, we give the Galois correspondence for covering spaces. This is actually somehow trivial.
In this post, we give the Galois correspondence for schemes over a field.
In this short post, we point out that the notion of connectedness of schemes is previously a special case of connected objects.
In this post, we discuss the fundamental theorem of Galois theory along the consideration of Galois connections.
I’m a graduated student from Nankai University. My main interesting is in category theory, algebraic geometry and number theory. I’ve held a reading group for couple of years and written lots of math notes. This site is planed to put them and post some short essays. It is welcome for anyone to point ...
