Re: [isabelle-dev] The Great Picard Theorem

2017-02-28 Thread Manuel Eberl
I'm not an expert in complex analysis either, but do remember that it
was briefly mentioned – but not proved – in my introductory lecture on
Complex Analysis when I was an undergratuate.

My intuition tells me that this is a very beautiful result, but not one
that you need a lot, but I could be wrong about this.

I could perhaps ask around a bit.

I for one am quite open to the idea of moving more material from the
distribution to the AFP, especially from HOL-Analysis. Picard's theorem
sounds like a reasonable candidate for that, but in general, I also have
no idea where to draw the line.

Cheers,

Manuel

[isabelle-dev] The Great Picard Theorem

2017-02-22 Thread Lawrence Paulson
I have just added this to the Analysis directory, making its inevitable 
refactoring more necessary.

Arguably it should be an AFP entry. Unfortunately, I’m not sufficiently expert 
in complex analysis to say whether it is core material or not. It looks like a 
fundamental result to me.

We should probably resolve the question of Analysis before the next release. 
How do we decide which things go into Complex_Main versus Analysis (which could 
be split into basic/advanced) and the AFP?
