anyone interested

I've been here before! I mean, I did try to set up non-commutative algebra&geometry sites before and sooner or later they always face the same basic problems :

a : dyspnoea : one person does not have enough fresh ideas to keep a mathematical site updated daily so that it continues to be of interest (at least, I'm not one of those who can).

b : claustrophobia : the topic of non-commutative algebra & non-commutative geometry is too wide to be covered (cornered) by one person. More (and differing) views are needed for balance and continued interest.

c : paranoia : if one is not entirely naive one has to exercise some restraint trying to protect ones research plans (or those of students) so the most interesting ideas never even get posted!

By definition, I cannot solve problems a) and b) on my own. All I can hope is that, now that the basic technological problems (such as including LaTeX-code in posts) are solved, other people are willing to contribute. For this reason I 'depersonalized' this blog : I changed the title, removed all personal links in the sidebar and so on. I want to open up this site (but as I said, I've tried this before without much success) to anyone working in non-commutative algebra and/or non-commutative geometry who is willing to contribute posts on at least a monthly basis (or fortnightly, weekly, daily…) for the foreseeable future. At the moment the following 'categories' of posts are available (others can be added on request) :

• courses : if you want to tell about your topic of interest in small daily or weekly pieces.
• columns : if you want to ventilate an opinion on something related (even vaguely) to na&g.
• nc-algebra : for anything on non-commutative algebra not in the previous categories.
• nc-geometry : for anything on non-commutative geometry not in the previous categories.
• this blog : for suggestions or explanations on the technology of this site.

Mind you, I am not looking for people who seek a forum to post their questions (such people can still add questions as comments to related posts) but rather for people active in na&g with a personal opinion on relevance and future of the topic.
If you are interested in contributing, please email me and we will work something out. I'll also post information for authors (such as, how to include tex, how to set restrictions etc.) in a sticky post soon.

Now, problem c) : in running sites for our master class on noncommutative geometry I've noticed that some people are more willing to post lectures notes etc. if they know that there is some control on who can download their material. For this reason there will be viewing restrictions on certain posts. Such posts will get a padlock-sign next to them in the 'recent posts' sidebar (they will not show up in your main page, if you are not authorized to see them). I will add another sticky on all of this soon. For now, if you would only be willing to contribute if there was this safeguard, rest assured, it will be there soon. All others can of course already sign-up or wait whether any of these plans (resp. day-dreams) ever work out….

update (febr 2007) : still waiting but the padlock idea is abandoned.
