Crab pulsar spectrum: a non-extensive approach
  Non extensive statistical physics has been applied to various problems in physics including astrophysics. In this paper we explore the possibility of using non extensive approach to explain the recently observed pulsed $\gamma$-ray from Crab pulsar above 100 GeV observed by VERITAS $\gamma$-ray telescope.
