The 2019 Geoquant activity will be co-organised by the National Tsing Hua University (NTHU)
The first week (September 2 - 6, 2019) will take place at the NTHU in Hsinchu. It will be a summer school addressing mainly students, post-docs and other researchers who are interested in entering the field.

The second week (September 9 - 13, 2019) will be an international conference. It will take place at the Jinshan Youth Activity Center at No.1 Qingnian Road, Jinshan District, New Taipei City.


Lecture courses

Each course will consists of 2-4 slots of one hour.

Abstracts of the lectures.

A printable information sheet about the school is here.

Practical Information

How to reach the places

Both the places of the school Hsinchu and of the conference Jinshan lie in an area close to the capital Taipei of Taiwan. In fact, Hsinchu is roughly 80 km southwest of Taipei, Jinshan is roughly 50 km northeast of Taipei.
The closest airports are
Recall that the school part (2-6.9., 2019) will be in Hsinchu at the National Tsing Hua University (NTHU) (101 Guangfu Road Section 2),
The conference week (9-13.9., 2019) will take place at the Jinshan Youth Activity Center at No.1 Qingnian Road, Jinshan District, New Taipei City.
Details how to reach these places from the airport and more information about public transportation can be found here.

The Hsinchu Guesthouse and the Student residence (see below) can be found on the jpg-map , respectively pdf-map . The Guest House I is at T212, the student residence is at D118, and the School site (where the lectures are -- General Building III, Dept of Math) is at T202.
In Jinshan you directly address to the reception. (In case needed their telephone number is 02 2498 1190 from within Taiwan and +886 2 2498 1190 from overseas).
The following bilingual note might be presented e.g. to taxi drivers.
There will be a bus organised between the school place and the conference place on Sunday 8.9.2019.


By default all participants in Hsinchu will be accommodated either in the guest house I of the NTHU or in the student residence (Dormitory Ching D118) (the students). respectively at the Jinshan Center. The reservation will be done on the basis of the registration on this webpage (see below). The prices for senior participants will be around 1600 - 1800 TWD. For students 800 - 1600 for single rooms respectively 500 - 1200 for shared rooms.
Arrival day for Hsinchu will be Sunday 1.9., departure day Sunday 8.9. (In fact the school will end on 6.7. - but the rooms in the guest house still can be used until 8.9.)
Arrival day for Jinshan will be Sunday 8.9., departure day Saturday 14.9. On the evening of 13.9. there is an activity to celebrate the mid-Autumn Festival.
For the participants supported by Taiwanese sources the accommodation will be paid directly.

Please pay attention to the warning on scam attacks at the beginning of the webpage.


For most of the participants holding a passport from Europe, USA and Japan there exists the possibility of a visa free entry. For details (maximal duration, validity of the passport) see .

Based on the information on the above webpage the visa free entry for Russians was extended until 31.7.2020. Also the maximal duration without visa for Russians was extended to 21 days.
See also here or the links below.

Getting entry permits to Taiwan for passport holders of mainland china is more involved and lengthy.
In particular, participants who have mainland China passports can not attend events using a tourist entry permit, even no support from Taiwan is given.
Information for those needing a visa can be found

Please contact Prof. Siye Wu at swu (at) for the necessary invitation letter.


Every participant needs to register via the following forms. On the basis of the registration data also the accommodation will be arranged.
The registration data is forwarded to the organisation committee and the participant will receive a notification about his/her acceptance (in due time) if you are not already an invited speaker.

If you are a senior participant please use this form .

If you are a young post-doc or a student, in particular if you want to apply for support then use this form.

There are only very limited funds for support available.
In case you want to present a poster presentation or a short talk, please submit the wish and the title on the registration page.
