One postdoctoral research position in the Sonata Bis grant Geometric structures behind tensors is offered at the Faculty of Mathematics, Informatics and Mechanics, University of Warsaw with Joachim Jelisiejew as the Principal Investigator.

Mathematically the project has two main lines of research

• tensors, including secant and cactus varieties, border rank, VSP, minimal border rank, asymptotic complexity etc.
• moduli of zero-dimensional objects: Hilbert and Quot schemes, commuting matrices, generalizations and application to algebraic geometry and complexity theory.

The successful candidate is expected to conduct research in one or both lines above. Apart from PI, the Warsaw group working on similar topics currently includes Weronika Buczyńska, Jarosław Buczyński, Stefano Canino, Cosimo Flavi, Francesco Galuppi, Jakub Jagiełła, Weronika Obcowska, Piotr Oszer, and Yuze Luan. It forms a part of larger Warsaw algebraic geometry group that is lead by in particular by Piotr Achinger, Adrian Langer, Andrzej Weber, and Jarosław Wiśniewski.

Francesco Galuppi also advertises a postdoc position at U. Warsaw, for tensors in algebraic geometry, see here. The deadline is 1 Mar 2025.
Other postdoc positions in Warsaw (deadline 26 Jan), at the Academy of Sciences, are advertised here.

Conditions and requirements

The official call is available from Euraxess, UW (see pages 5-9 for English version) and Nauka.gov.
The application should be sent directly to j.jelisiejew@uw.edu.pl no later than 15 February 2025. The starting date is 1 October 2025, but can be shifted by up to 4 months in either direction.
The position comes with no teaching obligations and with a travel and equipment budget.

The application should include

• CV, including publication list,
• Cover letter (max. 1 page, may include brief research plans),
• Names and email addresses of 2-3 researchers who will be asked for a letter of recommendation,
• Scan of signed acknowledgment of recruitment procedures (see example in the official call)
• Scan of signed personal data processing clause (see example in the official call)

The following are required

• A PhD in mathematics or equivalent obtained before the start of employment (in particular, the PhD can be obtained after the deadline of applications.)
• Research experience in algebraic geometry and/or commutative algebra,
• Good communication skills in English,
• Research experience in topics related to the project: tensors, deformation theory, moduli spaces, enumerative geometry etc. will be an advantage,

The position comes with an evaluation after one year, which, assuming reasonable research output, will be a formality.
