Re: Fibrations in a 2-category

[JeanBenabou <jean.benabou@wanadoo.fr>]

Dear David,

Thank you for your very kind offer. There are, at least, two reasons  
for which I'll have to think about it before I give an answer.

1- You say, I quote you:
"the input is no harder than writing in (La)TeX."
This seems to be very simple for you, but considering my very limited  
ability with computers (and this is an understatement) it will  
probably be almost impossible for me. For example I cannot type (La) 
TeX. If I need to have a text typed in TeX, I have to ask to a friend  
to type it for me. This is one of the reasons why I publish very  
little although I have many handwritten first drafts on various  
subjects in Category Theory.
2- Even assuming the friend would help me, the nLab is a wiki system,  
thus anybody would be able to modify my texts. And I'm sure I  
wouldn't like that. I'm not against discussion and I wouldn't object  
if one or many persons wrote their own texts, even if they are very  
critical of mine, provided they give mathematical arguments to  
justify their objections.

You might suggest solutions to 1 and 2, in which case I'd gladly  
accept your offer.

Thanks again, and best regards,

Jean
