Neither j, nor pj, nor pi occur in this formula. The right hand side does not depend on P. The value of c_i is not explained.
Please post, what you have tried so far and ask a specific question. Define all inputs of the formula, and nothing else, to reduce the level of confusion.

i is the index of elements of P,
P_ j is the value of P at position j
c_i is the number of elements of P satisfying the condition
{ j > i, p_j < p_i }
