Query: Symmetries of Multipartite Entanglement Evolution in Many-Sided Local
  Channels   Symmetries of the initial state of a quantum system and the quantum channels,
which simultaneously affect parts of the system, can significantly simplify the
description of the entanglement evolution. Using concurrence as the
entanglement measure, we study the entanglement evolution of few qubit systems,
when each of the qubits is affected by a local channel independently of the
others. We show that, for low-rank density matrices of the final quantum state,
such complex entanglement dynamics can be completely described by a combination
of independent factors representing the evolution of entanglement of the
initial state, when just one of the qubits is affected by a local channel.
