I will discuss quantum field theories that have quantum group as a global symmetry. Quantum group is a continuum deformation of Lie algebra, in the simplest case of SU(2). I will show that quantum groups act naturally on defect ending operators and even can transform a local operator into a defect ending one. I will then focus on a particular solvable 2D quantum field theory where the symmetry generators can be constructed explicitly.
