Description (last modified by )
With this ticket, through the methods :meth:`~sage.tensor.modules.free_module_tensor.FreeModuleTensor.display`
and :meth:`~sage.manifolds.differentiable.tensorfield.TensorField.display`
, SageMath is now able to compact the display of tensor product in the form dx^2
. In the case the frame element is something like f^2
, to avoid any misunderstanding in f^2^2
, one can set compact_product=False
in display to get the old displaying style f^2*f^2
.
Raising a tensor field to a given power is also possible now. When the tensor is an automorphism field the composition law of maps is used instead of tensor product and in this case, raising to a nonpositive power is possible.
