Title:  Spikes

Abstract: This talk will be a tutorial on spikes.  From a structural point of view it is hard to imagine a more benign class of matroids. However, everything goes wrong for spikes.

Title: Generalized quadrangles IV: classical families

Abstract: This week, we continue with our learning series on generalized quadrangles. We will give several classical constructions for generalized quadrangles.

Title: Aligned curves and height functions on Jacobians of curves

Title: Tree-chromatic number is not equal to path-chromatic number

Title: The typical structure of intersecting families

Title: Quantum walks III: strongly cospectral vertices

Abstract: This week, we continue with our learning series on quantum  
walks. We will look at strongly cospectral vertices.

Title: A branch-and-cut-and-price algorithm for the pollution routing problem

Title: Matroids with a spanning clique

Abstract: I will discuss a recent result on the structure of matroids that are spanned by the cycle matroid of a complete graph, and also put the result in the wider context of matroid structure theory for minor-closed classes.

Title: Generalized quadrangles V: GQs and quantum walks

Abstract: We will give another classical construction for generalized quadrangles. We will then explain a connection between quantum walks and generalized quadrangles.

Title: The quantum information cost of forgetting classical information
