Jordan curves inscribe a positive measure of rectangles

Joshua Evan Greene, Andrew Lobb

Suppose that is a Jordan curve of diameter which encloses a region of area . We prove that there exists a subset of measure at least…

Polynomial Inscriptions

Joshua Evan Greene, Andrew Lobb

We prove that for every smooth Jordan curve and for every set of six concyclic points, there exists a non-constant quadratic polynomial…

Square pegs between two graphs

Joshua Evan Greene, Andrew Lobb

We show that there always exists an inscribed square in a Jordan curve given as the union of two graphs of functions of Lipschitz constant less than . We are motivate…

Floer homology and square pegs

Joshua Evan Greene, Andrew Lobb

We construct a version of Lagrangian Floer homology whose chain complex is generated by the inscriptions of a rectangle into a real analytic Jordan curve. By using its associated s…

Special Alternating Knots are Band Prime

Joe Boninger, Joshua Evan Greene

We prove that a special alternating knot does not decompose as a non-trivial band sum. This restricts concordances from special alternating knots, and we conjecture that special al…

A spanning tree model for the Heegaard Floer homology of a branched double-cover

Joshua Greene

Given a diagram of a link K in S^3, we write down a Heegaard diagram for the branched-double cover Sigma(K). The generators of the associated Heegaard Floer chain complex correspon…
