ApCoA 2008: Workshop on
The main topic of the workshop is research pertaining to computations
with polynomials having approximate coefficients.
Those wishing to make an oral presentation at the workshop must also
contribute a corresponding written article: these may be either
original research or in the form of a tutorial/survey.
contributions will undergo the usual academic refereeing process,
and those accepted will be published in the proceedings as a
volume in the Springer "RISC Series".
ApCoA 2008 is co-organized by
RICAM (Radon Institute for Computational and Applied
Mathematics, Austrian Academy of Science)
is part of
Summer 2008 event.
The early registration fee is 100 Euros (within 24th of June
) and the late registration fee is 140 Euros.
The registration fee will cover the 3
lunches, the coffee breaks and the conference dinner.
Due to the limited number of rooms in the hotel in Hagenberg, register as soon as possible:

Transportation to Hagenberg
From railway station
There is a bus stop right next to the train station. It will take you
directly to Hagenberg. The ticket /person is 4.2 Euros.
The departure (for the direct connections) from the trainstation in Linz
is (schedule according to http://www.oebb.at
-- Linz Hauptbahnhof /
Hagenberg im Mühlkreis Ortsmitte): 06:00, 06:35, 07:35, 09:05, 11:05,
13:05, 14:05, 15:05, 16:05, 17:05, 18:05, 19:05, 20:15.
The bus number 310 leaves from the platforms C4-C5 of Linz Bus Station.
The bus station is located next to the train station. The easiest way is
to go out of the trainstation, arriving to the main entrance( where the
stone lions are ), and then got to the left. In the big covered hall are
all the platforms for the buses. The bus number 310 stops at platform
C4-C5. This bus brings you directly to Hagenberg. In Hagenberg, you
can leave the bus at the stop in front of the school (Volksschule) and
walk 100 m towards the church/castle to get to RISC, or 300 m on the
street and then turn left to get to Hotel Sommerhaus.
We did not receive enough requests to arrange 8-person taxies.
The distance between the airport and Hagenberg is around 40 km. A taxi
will cost up to 100 Euros to take you to Hagenberg.
The "Flughafenbus" goes to the main
train station of Linz and
costs 2,50 Eur. The bus stop is at the arrival hall. It departs (from
Monday to Saturday) every hour, starting from 06:00 until 19:00. Its
schedule is available at:
In 2006 the Radon Institute of Computational and Applied
of the Austrian Academy of Science and the Research Institute for
Computation (RISC) of the Johannes Kepler University in Linz, Austria
organized a "Special Semester on Groebner Bases and Related Methods"
designed and directed by Professor Bruno Buchberger, the inventor of
Groebner basis theory and method. The special semester consisted
a series of workshops on various aspects of the theory of Groebner
and on important applications of the method.
As part of this series, Prof. L. Robbiano conducted the Workshop B1
Commutative Algebra (during 20-24th Feb 2006).
