Evaluating contractions of a tensor product

Click For Summary
The discussion centers on evaluating the contractions of the tensor product T = δ ⊗ γ, where δ is the (1,1) Kronecker delta tensor and γ is a (0,1) tensor. The tensor product results in a (1,2) tensor, with components represented as T^a_{bc}. Two possible contractions are identified: T^a_{ab} and T^a_{ba}. Further evaluation of these contractions in terms of γ and δ is necessary for a complete understanding. The conversation emphasizes the need to clarify the results of these contractions.

Homework Statement


Consider ##T = \delta \otimes \gamma## where ##\delta## is the ##(1,1)## Kronecker delta tensor and ##\gamma \in T_p^*(M)##. Evaluate all possible contractions of ##T##.

Homework Equations



Tensor product

The Attempt at a Solution



##\gamma## is therefore a ##(0,1)## tensor and the tensor product with ##(1,1)## yields a ##(1,2)## tensor. The components of ##T## are therefore ##T^a_{\,\,\,\,\,bc}## which gives rise to the two possible contractions ##T^a_{\,\,\,\,\,ab}## or ##T^a_{\,\,\,\,\,ba}##. Do I need to include any more detail? Thanks.

I would say you also need to evaluate what these contractions actually are in terms of ##\gamma## and ##\delta##.
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
