Leipzig, Germany: Combinatorial Methods in AG and CA

The Max-Planck-Institute for Mathematics in the Sciences (MPI MIS) and the University of Leipzig are organizing a workshop on “Combinatorial Methods in Algebraic Geometry and Commutative Algebra”, that takes place at the Max-Planck-Institute from July 5th to July 7th, 2011.
Speakers will include:
– Winfried Bruns (Universität Osnabrück, Germany)
– Thomas Kahle (Institut Mittag-Leffler, Sweden, and Max-Planck-Institut für Mathematik in den Naturwissenschaften, Germany)
– Tim Römer (Universität Osnabrück, Germany)
– Bernd Sturmfels (University of California, USA)
– Santiago Zarzuela (Universitat de Barcelona, Spain)
Further information about the workshop, including online registration, can be found on the webpage for the workshop.

Cankiri, Turkey: Combinatorics, Algebra, Geometry

A workshop entitled “Karatekin Math Days: Combinatorics, Algebra, Geometry and Interactions” will be held in Cankiri/TURKEY on June 20-24, 2011. There will be four mini courses, several invited talks, a limited number of contributed talks and a poster session. For more information, see the workshop’s web page: http://matematik.karatekin.edu.tr/KMD2011.html.

Leuven, Belgium: Toric geometry

Toric geometry and applications
Leuven, Belgium, 6 – 10 June 2011
The goal of this meeting is to bring together researchers from a wide range of topics in toric geometry, such as
The geometry of toric varieties,
Effective aspects of toric geometry,
Toric geometry and mirror symmetry,
Tropical geometry and algebraic statistics,
Toric and arithmetic geometry.
The research lectures on some of these topics will be preceded by an introductory lecture by an expert.
For more information on this meeting, see the website or the poster.

Purdue: Algebra and Geometry

The “Midwest Commutative Algebra and Geometry Conference”, organized by Alberto Corso, Claudia Polini, Bernd Ulrich and Yu Xie, will be held at Purdue University (West Lafayette, Indiana) during the period May 22 – 26, 2011.
This conference continues a well established tradition of Commutative Algebra and Algebraic Geometry meetings in the Midwest. Young mathematicians are especially encouraged to attend. There is a limited amount of support provided by the National Science Foundation through the Special Algebra Meetings in the Midwest grant (NSF DMS-0753127). The deadline for being considered for financial support is April 15, 2011.

Daniel Quillen

We have learned that Daniel Quillen passed away recently. The message below was posted to a topology listserve by his widow.

Dear friends and colleagues,
My husband of almost 50 years, Daniel Gray Quillen died quietly and peacefully on Saturday morning around 7 AM, April 30, 2011 at the age of 70. He is finally at rest and no longer suffering. In the last week of his life he was wonderfully cared for by the people of Haven Hospice. My son David, daughter-in-law Amy, daughter Cindy and I were constantly at his side. Dan died from the final stages of Alzheimer’s and the associated complications. We were able to follow his wishes of comfort and not making his suffering last any longer than nature had planned.
Alzheimer’s is truly a terrible disease. It was very hard to watch what it did to Dan over the past 5+ years. It stole the things he loved and took him from me too early. It first took his ability to do mathematics, then ability to play music, read, rational thinking and finally recognition of those he loved (except me, thank goodness).
I have no plans for an organized service. Dan’s body has been donated to medical science, following his clear and long standing wishes. If the mathematics community would like to organize a memorial service or a memorial colloquium we would be very pleased.
Please do not send flowers. I don’t know what I would do with them. If people feel that they would like to do something, I would very much support any assistance to your local hospice or to or Alzheimer’s research.
The work that hospice does in amazing and finding an answer to this awful disease is unbelievably important.
Thank you for all your support and friendship recently and for almost 50 years.
