Effective Whitney Stratification of Real Algebraic Varieties
Martin Helmer, Anton Leykin, Vidit Nanda
We describe new algorithms to compute Whitney stratifications of real algebraic varieties. Using either conormal or polar techniques, these algorithms stratify a complexification o…
Multilinear Hyperquiver Representations
Tommi Muller, Vidit Nanda, Anna Seigal
We count singular vector tuples of a system of tensors assigned to the edges of a directed hypergraph. To do so, we study the generalisation of quivers to directed hypergraphs. Ass…
Harder-Narasimhan Filtrations of Persistence Modules
Marc Fersztand, Emile Jacquard, Vidit Nanda +1
The Harder-Narasimhan type of a quiver representation is a discrete invariant parameterised by a real-valued function (called a central charge) defined on the vertices of the quive…
