    The aim of this paper is to present a simple calibration method aimed at optimizing the kinematical invariants of a whole body motion capture model, meaning limb lengths and some of the marker placements. A case study and preliminary results are presented and give encouraging insights about the generalized use of such a method in motion analysis in sports

    Tropical patterns from the Fock-Goncharov pairing and Ringel's conjectures

    We study tropical friezes and cluster-additive functions associated to symmetrizable generalized Cartan matrices in the framework of Fock-Goncharov duality in cluster algebras. As a special case, we generalize and prove two conjectures of C. M. Ringel on cluster-additive functions for arbitrary Cartan matrices of finite type
