(05.06.) Kinematic algebras in scattering amplitudes

We will describe the appearance of certain algebraic structures in
the kinematic dependence of scattering amplitudes, both in gauge
theory and in gravity. These structures mirror the colour dependence
of the amplitude in the case of gauge theory, making the so-called
colour/kinematics duality manifest. We will mainly focus on the
kinematic algebras arising from the recently proposed scattering
equations, which give a decomposition of the amplitude into simpler
building blocks. We will also briefly discuss a different realisation of
the kinematic algebra, inspired by the geometry of Lie groups.
