Can you expand them to single operations? Thanks.

Hi , Thanks. ##p_i## is the component of a vector in the ##\bf_i## direction. Also ##\epsilon_{ijk}## is the permutation operator. ##u_{i,j}## is ##\frac{du_i}{dx_j}##.

TL;DR Summary: My problems comes to a vector expression which needs to be simplified I got an expression pi=εijksk,lul,j Here s and u are two vectors. What will be the vector expression of this vector p with curl s, curl u, and other operations?
