Piecewise circular curves and positivity

Jean-Philippe Burelle, Ryan Kirk

We introduce the moduli space of generic piecewise circular $n$ -gons in the Riemann sphere and relate it to a moduli space of Legendrian polygons. We prove that when $n = 2 k$ , this m…

Continuity properties of vectors realizing points in the classical field of values

Dan Corey, Charles R. Johnson, Ryan Kirk +2

For an $n$ -by- $n$ matrix $A$ , let $f_{A}$ be its "field of values generating function" defined as $f_{A} : x \mapsto x^{*} A x$ . We consider two natural versions of the continuity, whic…
