Announcements

First Announcement (March 21, 2011)

Dear Colleague:

It is a pleasure to announce the 11th edition of ALGA, the Brazilian meeting on Algebraic Geometry and Commutative Algebra. It will be in Maresias, on the coast of the State of São Paulo, in Maresias Beach Hotel (http://www.maresiashotel.com.br/new), from October 16 to 22, 2011. As you might know already, the ALGA meetings have been for years gathering points for those in the field in Brazil and their present and future collaborators from abroad. For their history, please see:

Second Announcement (September 5, 2011)

Dear Colleague:

This is the second and last general announcement of the 11th edition of ALGA, the Brazilian meeting on Algebraic Geometry and Commutative Algebra, to take place in Maresias, on the coast of the State of São Paulo, at Maresias Beach Hotel (http://www.maresiashotel.com.br/new), from October 16 to 22, 2011. There is a home page, permanently in construction and hopelessly outdated, at http://impa.br/opencms/pt/eventos/store/evento_1114

If you would like to take part in the meeting, please let us know by replying to this message.

Some practical information:

1) Registration:

You are automatically registered if you accepted our invitation to speak or to present a poster. Everyone else must register by sending a message to alginrio@impa.br. At any rate, EVERYONE must (please) tell us:

– Your full name,
– Your nationality, – The university or institute you are affiliated to,
– Your address (or that of the university or institute you are affiliated to)
– Your passport number or CPF (Brazilian fiscal code),
– If arriving by plane to Guarulhos or Galeão, the air company, the flight number and the virtual (some call it expected) arrival date and time.

Please register by September 16 to receive further announcements. If you want to register by phone, call me at +55-21-2529-5218, but DON’T trust your message to the answering machine.

2) Financial help:

If you would like to ask for financial help, please let us know by September 16. All speakers and poster presenters will be offered funds to help cover accommodation costs. If you haven’t been offered funds for air travel, please do not ask us for them. We will be able to offer help to cover accomodation costs to selected participants. You will know whether you have been selected for financial help by September 21. In principle, due to restrictions on the usage of the funds we have access to, you will be offered at most 187 reais per day, for at most 6 days. We may be able to cover more for selected participants.

3) Accomodation costs:

The hotel charges (taxes included) per day are:

Single apartment: R$250,00
Double apartment: R$170,00 for each of the two occupants
Triple apartment: R$145,00 for each of the three occupants

The charges include room for a night, dinner, breakfast and lunch. So, those staying for the whole duration of the meeting, from Sunday evening to Saturday morning, thus paying for six days, will have all the meals covered from dinner on Sunday to lunch on Saturday. We must be informed of the type of apartment you will want by September 26. Unless you let us know explicitly that you do not trust us (no bad feelings), or let us us know about your roommates, if you choose a double or triple apartment, we will select other participant(s) to accommodate you with.

4) Transportation:

There will be a bus (or minibus, or van) leaving Guarulhos airport, in São Paulo, to Hotel Maresias on Sunday 16, and returning on Saturday 22. Likewise, there will be a bus leaving the city of Rio de Janeiro to Hotel Maresias on Sunday 16, and returning on Saturday 22. Here are their schedules (all times in 24h format):

Sunday 16:

Guarulhos -> Maresias: leaving at 12:30
Rio de Janeiro -> Maresias: leaving at 9:30

Saturday 22:

Maresias -> Guarulhos: leaving at 11:00
Maresias -> Rio de Janeiro: leaving at 11:00

The trip to Maresias from Guarulhos takes 3 hours. That from Rio de Janeiro may take 8 hours. Details as specific departure points will be given later. Those planning to arrive by plane on October 16 should use the Guarulhos bus. If you plan to use any of these buses, please let us know by September 26, letting us know: 1) which bus you are going to use TO Maresias and 2) which bus you are going to use FROM Maresias. We will decide on the size of each bus according to the information all of you give us, so if you reply to us late, there may not be space for you!

5) Registration fee:

It is likely there will be a registration fee, as we may not be able to cover some costs with the funds we have access to. How much is yet to be determined.

If you have any questions, please do not hesitate to contact us at alginrio@impa.br or me by phone at +55-21-2529-5218.

Best regards,

Eduardo.(For the organizing committee: Carolina Araujo, Eduardo Esteves (IMPA) and Marcos Jardim (UNICAMP))
