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…
Conormal Spaces and Whitney Stratifications
Martin Helmer, Vidit Nanda
We describe a new algorithm for computing Whitney stratifications of complex projective varieties. The main ingredients are (a) an algebraic criterion, due to Lê and Teissier, whic…
Complex Links and Hilbert-Samuel Multiplicities
Martin Helmer, Vidit Nanda
We describe a framework for estimating Hilbert-Samuel multiplicities for pairs of projective varieties from finite point samples rather than defining equations…
The devil is in Asymmetries (Rough Version)
Edinah K. Gnang, Vidit Nanda
We formally investigate some computational obstacles to tractability of computing the variety determined by K complex polynomials in N boolean variables. We show that using algebra…
