<br>
Let's meet again this Tuesday at 1pm, those of us who can. I plan no <br>
structured part - I realized last week that we had plenty to talk about <br>
(esp about the seminars), and that some people had to leave at 2pm. I'll <br>
send a link on Tuesday - we'll have the Tue seminar link as default, but <br>
may send another (I want to make sure the glitch I had last time that <br>
made us switch linkscsd will not happen).<br>
<br>
Another thing - This Tuesday seminar, by Lisa, will be given on the <br>
board at the seminar room! So, I encourage those of you who feel <br>
comfortable to be in the audience. I plan to be there.<br>
<br>
Best,<br>
<br>
Avi<br>

PS For those of you who missed (all or part) of Visu's presentation last <br>
week in the group meeting, he'll be happy to share his slides and <br>
discuss them with anyone intersted. Briefly, he talked about <br>
"equivalence problems" (or isomorphism problems or word problems), which <br>
apear everywhere mathematics. He exemplified that in many there is (in <br>
some cases obvious, in some cases hidden) a group action, and how <br>
invariant theory and complexity theory combine to give new progress on <br>
some of them.<br>
