Konferanser

Temaet for konferansen i ?r er klimapolitikk og klimainvesteringer. Innledere vil v?re John Hassler (Professor i samfunns?konomi ved Stockholms universitet), Bj?rnar Baugerud (Leder for klimainvesteringsfondet/NorFund), Steinar Holden (Professor ved ?konomisk institutt, UiO) og Kristin Halvorsen (Direkt?r ved Cicero Senter for klimaforskning).

In a circular economy, products and services are designed for longevity, reuse, and recycling. It contrasts with the traditional linear economy by promoting a closed-loop system where materials are kept in circulation, reducing environmental impact and depletion of raw materials.

Title:  ¡®Tipping points¡¯ confuse and can distract from urgent climate action

Speaker: Elisabeth Gilmore, Carleton University

Positroids are a class of matroids that were introduced by Postnikov in 2006 that index a certain stratification of the totally non-negative Grassmannian. These matroids are famously in bijection with a ¡°zoo¡± of combinatorial objects including Grassmann necklaces and plabic graphs. We introduce a new family of positroids called rook matroids that arise from restricted rook placements on a skew shaped board and discuss it in terms of this zoo. We highlight the transversal structure of rook matroids and the slightly mysterious relationship they share with lattice path matroids. This is joint work with Per Alexandersson and ongoing work with Irem Portakal and Akiyoshi Tsuchiya.
