class_docstr: Base class to represent the So2 group.
  
  The SO(2) is the group of all rotations about the origin of two-dimensional Euclidean space
  :math:`R^2` under the operation of composition.
  See more: https://en.wikipedia.org/wiki/Orthogonal_group#Special_orthogonal_group
  
  We internally represent the rotation by a complex number.
  
  Example:
      >>> real = torch.tensor([1.0])
      >>> imag = torch.tensor([2.0])
      >>> So2(torch.complex(real, imag))
      Parameter containing:
      tensor([1.+2.j], requires_grad=True)
docstr: Returns the inverse transformation.
  
  Example:
      >>> s = So2.identity()
      >>> s.inverse().z
      Parameter containing:
      tensor(1.+0.j, requires_grad=True)
