class_docstr: Hawkes kernel for power law
  
  .. math::
      \phi(t) = \phi(t) = \alpha (\delta + t)^{- \beta} 1_{t > 0}
  
  Where :math:`\alpha` is called the multiplier, `\delta` the cut-off and
  :math:`\beta` the exponent
  
  Parameters
  ----------
  multiplier : `float`
      Multiplier of the kernel, also noted :math:`\alpha`
  
  cutoff : `float`
      Cut-off of the kernel, also noted :math:`\delta`
  
  exponent : `float`
      Exponent of the kernel, also noted :math:`\beta`
