Curl index notation
WebJun 21, 2024 · 1 Answer. Sorted by: 3. The vector-valued curl can be written in index notation using the Levi-Civita tensor. c k = ( ∇ × A) k = ( ∇ i A j) ε i j k = ε k i j ( ∇ i A j) c = ∇ × A = ( ∇ A): ε = ε: ( ∇ A) where the colon denotes the double-dot product. The matrix-valued gradient can also be written in index notation. Webinstead. (They are called ‘indices’ because they index something, and they are called ‘dummy’ because the exact letter used is irrelevant.) In index notation, then, I claim that the conditions (1.1) and (1.2) may be written e^ i^e j = ij: (1.3) How are we to understand this equation? Well, for starters, this equation
