What it is
A mathematical notation for tensors and spinors that uses indices merely as type markers, without reference to components in a particular basis, developed by Roger Penrose.
What it led to
- Rigorous formalization of tensor calculus in general relativity
- Widespread use in mathematical physics and differential geometry
- Basis of Penrose and Rindler's book 'Spinors and Space-Time'
