We are happy to report that Peter Bürgisser has been awarded an ERC Advanced Grant for his project COCAN: Complexity and Condition in Algebra and Numerics. This provides funding for basic research in the amount of 2.3 million Euro for five years.

### Workshop "Optimization, Complexity and Invariant Theory" at Princeton

Dienstag, 20. Februar 2018

From the 4th until the 8th of June, it will take place at the Institute of Advanced Study at Princeton the workshop "Optimization, Complexity and Invariant Theory" organized by Prof. Avi Widgerson. This workshop will explore "the connections between complexity and optimization with algebra and analysis, which have emerged from the works on operator scaling". Registration is for free. More information in this link.

### Felipe Cucker Becomes New Einstein Visiting Fellow

Freitag, 02. September 2016

The BMS will welcome Prof. Felipe Cucker from City University Hong Kong as the new Einstein Visiting Fellow in January 2017. Cucker will set up his research group at TU Berlin while continuing his professorship at City University. One postdoc position and two PhD scholarships will be offered within Cucker's Einstein Visiting Fellowship "Complexity and accuracy of numerical algorithms in algebra and geometry" for the period 1 January 2017 to 31 December 2019. More details and information on how to apply can be found here.

### No occurrence obstructions in Geometric Complexity Theory

Donnerstag, 21. April 2016

Valiant's algebraic version of the P vs. NP problem (VP vs. VNP) cannot be resolved by exhibiting representation-theoretic occurrence obstructions in the sense of Mulmuley and Sohoni. This has been recently shown by Peter Bürgisser in collaboration with Christian Ikenmeyer and Greta Panova, see [arXiv:1604.06431]. The paper has been accepted for publication in FOCS 2016.

### Complete Solution of Smale's 17th Problem

Donnerstag, 19. Mai 2016
