      abstract     = {Active matter agents consume internal energy or extract
                      energy from the environment for locomotion and force
                      generation. Already, rather generic models, such as
                      ensembles of active Brownian particles, exhibit phenomena,
                      which are absent at equilibrium, particularly
                      motility-induced phase separation and collective motion.
                      Further intriguing nonequilibrium effects emerge in
                      assemblies of bound active agents as in linear polymers or
                      filaments. The interplay of activity and conformational
                      degrees of freedom gives rise to novel structural and
                      dynamical features of individual polymers, as well as in
                      interacting ensembles. Such out-of-equilibrium polymers are
                      an integral part of living matter, ranging from biological
                      cells with filaments propelled by motor proteins in the
                      cytoskeleton and RNA/DNA in the transcription process to
                      long swarming bacteria and worms such as Proteus mirabilis
                      and Caenorhabditis elegans, respectively. Even artificial
                      active polymers have been synthesized. The emergent
                      properties of active polymers or filaments depend on the
                      coupling of the active process to their conformational
                      degrees of freedom, aspects that are addressed in this
                      article. The theoretical models for tangentially and
                      isotropically self-propelled or active-bath-driven polymers
                      are presented, both in the presence and absence of
                      hydrodynamic interactions. The consequences for their
                      conformational and dynamical properties are examined, with
                      emphasis on the strong influence of the coupling between
                      activity and hydrodynamic interactions. Particular features
                      of emerging phenomena in semi-dilute systems, induced by
                      steric and hydrodynamic interactions, are highlighted.
                      Various important, yet theoretically unexplored, aspects are
                      featured, and future challenges are discussed.},
