PostDoc position in Algorithms at IDSIA, USI-SUPSI, Lugano, Switzerland
The Algorithms and Complexity Group of IDSIA, USI-SUPSI, Lugano (Switzerland), opens 1 postdoc position for up to 4 years supported by the Swiss National Science Foundation project "Ideal Membership Problems and the Bit Complexity of Sum of Squares Proofs", project n. no 200021_207429 / 1.
The group currently consists of 2 PhD students, an IDSIA researcher, Prof. Mastrolilli, and we collaborate with 2 well-known researchers in the field. The ideal candidate will be expected to collaborate and work within this group.
The project is on the interface of three very active areas of research in theoretical computer science and mathematics.
<![if !supportLists]>1. <![endif]>The first one deals with polynomial ideals and their properties and goes all the way back to David Hilbert.
<![if !supportLists]>2. <![endif]>The second one is a widely used tool in complexity, algebraic and semi-algebraic proof systems such as Sum-of-Squares (SoS), where the main question is when a proof of a certain property of a polynomial can be efficiently found.
<![if !supportLists]>3. <![endif]>The third area is the analysis of the complexity of constraint satisfaction problems (CSPs), mainly through the universal-algebraic approach.
These areas address key problems in theoretical computer science, they produce a very significant amount of world class research, with many publications in world-leading venues in theoretical computer science.
The proposed project is about a new direction of research combining these three areas mentioned above. This new direction of research was recently initiated by the PI in a series of publications and followed up by other works by world-leading experts on universal-algebraic methods in CSPs. The new direction proposes to combine two widely used methodologies in a new way, with an algebraic geometry view used to bring them together. This new combination opens a whole range of new very interesting problems.
