In Graz (city and TU Graz) and when entering Austria
there are no restrictions that I am aware of. No masks required.
(Airlines or train companies outside Austria
might have their own restrictions.)
However, the incidence figures are increasing again since end of May, due to the new variants Ba.5.
We have chosen large lecture rooms so that distance keeping is possible.
We will have invited talks of about 45-50 minutes by
Rainer Dietmann, Florian Luca, Igor Shparlinski, Cathy Swaenepoel, Arne Winterhof,
and further talks
by Michael Drmota, Lukas Spiegelhofer, Kübra Benli,
Pierre Bienvenu, Andrei Shubin, Paul Peringuey
So far my question about open problems did not reveal much.
Please let us (CE and TS) know if you would like to present one.
We can have an open problem session, even though maybe it is very brief only.
The workshop is on 1.+2. July, roughly from 8.45 to 17.00.
The conference takes place at TU Graz (Steyrergasse 30, go up one level,
though it is somehow the groundfloor of that building. Lecture room HS BE01).
(Part of our institute is in this building, another part in Kopernikusgasse 24).
Here is a link to the building/lecture room
link to HS BE01,
Other rooms, for small group discussions
I have also reserved the two seminar rooms opposite of HS BE01, (SR AE02 and SR AE06)
and also the Number theory seminar room at Kopernikusgasse 24.
(Please note that on Friday afternoon the main lecture room HS BE01 is used for an exam.)
Closest tram stop
Next tram stop is "Neue Technik" on line 6.
(From Hauptplatz to Steyregasse 30 at most 20 minutes walk, from Jakominiplatz at most 15 minutes,
from Hotel Göllner at most 10, from Dietrichsteinplatz at most 8 minutes walk.)
Walking routes from Hauptplatz (Jakomiplatz, Dietrichsteinplatz is on the route)
Some other ArithRand participants (who cannot travel to Graz) might be online.
There will not be any recording, and the video is only accessible to ArithRand colleagues.
DINNER on July 1st
July 1st, 19.00: I have reserved at
"L'Osteria", Mehlplatz 1 .
This is Italian style (though not actually Italian), it's famous for its superlarge pizzas,
(it's fine to share the pizza: one pizza, two plates), but of course you also get
many other dishes. (Please pay for your own consumption.)
Map to L'Osteria
On Friday there are lots of lunch options nearby,
including at the "Mensa (rooftop)" (superb view over the city,
1 minute from Steyrergasse 30, or many places on Münzgrabenstrasse).
On Saturday, there are less options, but Münzgrabenstrasse still has sufficiently many open places.
We decided to go for a minimalistc coffee solution:
In Steyergasse 30 basement, one level below the conference, there is a coffee machine (coins needed).
In Kopernikusgasse 24, 2nd floor in our institute's coffee room there is a machine.
It's about 5 minutes walk.
Paul and Bohne (closed on saturday), Schörgelgasse 34, also 5 minutes walk.
TRAVEL/Public Transport/Car parking
From the train station (Graz Hauptbahnhof):
outside the train station there are escalators down to the tram lines.
(choose the one to the right for the city centre). Buy a ticket for 2,50. All tram lines (1,4,6,7) go to Hauptplatz and Jakomiplatz, and
line 6 even to Dietrichsteinplatz and Neue Technik.
From Airport to the the city centre:
Most CO_2 and cost efficient (2,50 Euro):
there is a bus stop directly in front of the Airport exit.
(The website below lists quite regular routes with bus number 630 to Puntigam Bahnhof
(make sure it goes in THAT direction, as the bus in the opposite direction also stops there),
and then change to line 3/5 (very frequently, in case the recommended connection is missed).
For late arrivals a taxi is the only option.
(if there are no on the taxi rank in front of the exit: one of the largest campanies is 878, phone number "++43 316 878".)
A train stop is about 5 minutes walking from the airport.
(This goes for example to Graz Hauptbahnhof (main station).
Here is a link to
local public transport
(for example type in Flughafen Graz and Dietrichsteinplatz (e.g. for Hotel Göllner, or Jakominiplatz, or so))
and update the date to 30.6.

In the city centre there are a few short tram routes free
The definition of that small network is "all tram stops that are (in any reasonable metric) distance 1
from Jakominiplatz or Hauptplatz". The longest possible distance is 3 stops (within that network!).
For example the route Dietrichsteinplatz-Jakominiplatz-Hauptplatz is free.
(This does not mean that other routes of lengths 1,2,3 etc are free...)
- CAR PARKING
Car parking may be possible on campus, please contact
(with dates, and car licence number) as soon as possible.
If you have time left beyond maths and sightseeing in the city centre:
Let's enjoy the conference, and let's be glad that travel is possible this year!
- The tourist office is at Herrengase 16.
- The museum
directly at the tourist information is quite unique,
(supposedly the world's largest collection of old weapons.)
- The Dome is newly restaurated.

from the Schlossberg (5 Euros, plus elevator if you use it).
