Still no new blogging

  • June 28th, 2007

Too harried to blog.

Will miss this carnival.

Bugger.

Carnival of Mathematics 10

  • June 15th, 2007

Is now up at Math Notations. The current host further suggests a split in undergrad+ and undergrad- categories – with the simpler and didactics focused posts in one carnival and the research and/or advanced mathematical posts in another. Personally, I think the momentum the carnival has is a good thing, and that a split should wait until we habitually turn away more posts than we’re comfortable with. This volume is not yet actually there – wherefore I’d be against a split.

Enjoy.

And the published version is…

right here – at least if you’re wondering what happened with my recent interview.

Linking in hushed voices

  • June 12th, 2007

All the cool kids are doing it, so I’ll tag in too.

There’s a secret blogging seminar going on. And the people seem to be writing interesting things – what little they managed to write before the hushed rumour mill started.

Enumerating the Saneblidze-Umble diagonal in Haskell

  • June 11th, 2007

IMPORTANT: Note that the implementation herein is severely flawed. Do not use this.

One subject I spent a lot of time thinking about this spring was taking tensor products of A∞-algebras. This turns out to actually already being solved – having a very combinatorial and pretty neat solution.

Recall that we can describe ways to associate operations and homotopy of associators by a sequence of polyhedra Kn, n=2,3,.., called the associahedra. An A∞-algebra can be defined as being a map from the cellular chains on the Associahedra to n-ary endomorphisms of a graded vector space.

If this was incomprehensible to you, no matter for this post. The essence is that by figuring out how to deal with these polyhedra, we can figure out how to deal with A∞-algebras.

Own a funny tshirt? Please leave our country.

So, Heiligendamm just outside Rostock in northern Germany these days hosts both the G8 meeting and the numerous protest activities. This setup would have me ranting on and on about the violent left and failure to admonish extremists on your own side.

But that is not the issue that makes me reach for my keyboard.

Swedish news outlets report today about Tomas Eriksson, a swedish lawyer who came on the ferry from Trelleborg with his girlfriend yesterday morning.

In the entry checks, the German border officials found a t-shirt in the girlfriends luggage, with the symbol of the swedish political pro-media-piracy lobbying organisation “Piratbyrån”. A black tshirt, with the following logo printed in white:
Piratbyrån

T’bilisi and Carnival # 9

  • June 2nd, 2007

First off, I have a travellog of sorts over at my Livejournal.

Further on, jd2718 just posted the newest Carnival of Mathematics, as so often otherwise, I do feature.
