Critical Points of Degenerate Metrics on Algebraic Varieties: A Tale of Overparametrization

Giovanni Luca Marchetti, Erin Connelly, Paul Breiding +1

We study the critical points over an algebraic variety of an optimization problem defined by a quadratic objective that is degenerate. This scenario arises in machine learning when…

Geometric Interpretations of Compatibility for Fundamental Matrices

Erin Connelly, Felix Rydell

In recent work, algebraic computational software was used to provide the exact algebraic conditions under which a sixtuple ${F^{ij}}$ of fundamental matrices, corresponding to $4…

Lines, Quadrics, and Cremona Transformations in Two-View Geometry

Erin Connelly, Rekha R. Thomas, Cynthia Vinzant

Given $7 \leq k \leq 9$ points $(x_{i}, y_{i}) \in P^{2} \times P^{2}$ , we characterize rank deficiency of the $k \times 9$ matrix $Z_{k}$ with rows $x_i^\top \otimes y_i^\t…

The Geometry of Rank Drop in a Class of Face-Splitting Matrix Products

Erin Connelly, Sameer Agarwal, Alperen Ergur +1

Given $k \leq 6$ points $(x_{i}, y_{i}) \in P^{2} \times P^{2}$ , we characterize rank deficiency of the $k \times 9$ matrix $Z_{k}$ with rows $x_{i}^{⊤} \otimes y_{i}^{⊤}$ in…

Universality in perfect state transfer

Erin Connelly, Nathaniel Grammel, Michael Kraut +2

A continuous-time quantum walk on a graph is a matrix-valued function $exp (- i A t)$ over the reals, where $A$ is the adjacency matrix of the graph. Such a quantum walk has…
