Homework Help: Levi-Civita 4D

  1. Oct 2, 2013 #1
    1. The problem statement, all variables and given/known data

    I was following this book "problem book in quantum field theory by voja radovanovic" and I got stuck in the following problem

    Prove [itex]\epsilon_{\alpha\beta\gamma\delta}A_{\,\nu}^{\alpha}A_{\,\mu}^{\beta}A_{\,\lambda}^{\gamma}A_{\,\sigma}^{\delta}=\epsilon_{\mu\nu\lambda\sigma}\det\left(A\right)

    2. Relevant equations

    A is a matrix and in the left-hand side we have the components of this matrix

    3. The attempt at a solution

    I've tried to write an explicit form for the determinant using


    but i didn't find anything useful. Any help or tip would be appreciated

    Thank you
