It is common convention to use greek indices when writing expressions involving tensors in Minkowski space, while Latin indices are reserved for Euclidean space. Well-formulated expressions are constrained by the rules of Einstein summation: any index may appear at most twice and furthermore a raised index must contract with a lowered index ...

Adding display=inline renders exponents lower, especially under square roots, often resulting in a smaller square root which fits better in inline text: compare <math> \sqrt {x ^ 2+y ^ 2} </math> to <math display=inline> \sqrt {x ^ 2+y ^ 2} </math> which render as + and +, respectively.
The specificity describes how closely the index terms match the topics they represent [10] An index is said to be specific if the indexer uses parallel descriptors to the concept of the document and reflects the concepts precisely.
