#### Stevens Institute online International Group Theory Seminar

The
Algebraic Cryptography Center at Stevens Institute has the continuing online International Group Theory Seminar. These seminars are "webinars" and use the Wimba conferencing system.
The seminar resumes January 20, 2011. Further additional information can be found at http://www.stevens.edu/algebraic/GTI/ Jan 20.

#### Dani Wise speaks at Columbia Friday Jan 14th

There's a special seminar by Dani Wise this coming Friday (at the regular time, 1:20 PM) at Columbia in room 520. Title: Morse Theory, Random Subgraphs, and Incoherent Groups Abstract:
I will use the "probabilistic method" to prove that certain polygons of
finite groups have finitely generated subgroups that are not finitely
presented. This gives a new family of incoherent Kleinian groups. I'll
try to give an idea of what I'm doing here, and perhaps what to expect
next. http://math.columbia.edu/~gtseminar/ |

#### The new grouptheory.org web site

Our new web site for the group theory cooperative has been built by Katherine St. John who has generously given her time and expertise and which has made the construction of the site both painless and possible. |
