hi cosmo-torun, Sorry for the late warning, but i'm not the organiser of KRA seminars! So the plan now is: "Ksztalt Wszechswiata" = seminar on PDS @KRA 10.15 Fri 24.10.2008 = today if you read your email daily. The content will be mostly on http://arXiv.org/abs/0801.0006 since i just read the email confirming what i thought had been put off to some unknown date until just a few minutes ago. That should be enough for a decent presentation and discussion in any case, IMHO. :) As usual, i imagine a poster was put up in KRA just yesterday Thursday, with no email reminder on our KRA internal mailing list.... pozdr boud
