Interpolation in variable exponent spaces

  • Alexandre AlmeidaEmail author
  • Peter Hästö


In this paper we study both real and complex interpolation in the recently introduced scales of variable exponent Besov and Triebel–Lizorkin spaces. We also take advantage of some interpolation results to study a trace property and some pseudodifferential operators acting in the variable index Besov scale.
