TU Braunschweig, Germany, February 26 – 27, 2026

We organize the interdisciplinary mathematical workshop Positivity, Convexity and Computation in Rigidity Theory to take place on February 26 – 27, 2026 at Technische Universität Braunschweig. With this workshop we want to bring together researchers with interest and expertise in questions of geometric rigidity theory, with experts concerned with positivity, convexity, symmetry and computations in the realm of real algebraic geometry.

Our goal is to combine the expertise from these deeply intertwined topics to encourage the development of novel solution strategies that help to solve geometric problems from rigidity theory, as well as to provide meaningful and difficult examples to test existing approaches on.

We plan to have an open problem session to get to know some relevant and tractable problems from the field. A sketch of our scientific vision for the workshop and some exemplary problems can be found here!

Moreover, we prepared a promotional for the workshop which you can download here.
