Question
These mathematical objects are essentially equivalent to multilinear maps. For 10 points each:
[10m] Name these objects, whose physical instances include the rank-two "stress-energy" example of them.
ANSWER: tensors [or stress-energy tensor]
[10h] Objects similar to tensors, except for the fact that their sign flips after undergoing an improper rotation, are described by a term in which "tensor" is preceded by this prefix.
ANSWER: pseudo- [or pseudotensor]
[10e] This is the simplest example of a transformation that flips the sign of a pseudotensor. In two dimensions, these geometric transformations are defined with respect to a "mirror line."
ANSWER: reflections [or reflecting or reflected]
