Do you know if there is any command to write "Hess f"? What is the standard? Should I just write it as text?

Thank you!

  • You made an error in your command, @Bernard, it should be \DeclareMathOperator{\hess}{Hess}. You forgot a { again! – Clément Feb 26 '16 at 15:07

    Anyway, I'll remove my comment, since there's an answer now. Thanks for being watchful! – Bernard Feb 26 '16 at 15:18

The following will work nicely:



  (\Hessian f)_{ij} &\equiv \frac{\partial^{2} f}{\partial x_{i} \partial x_{j} } \\
  \Hessian\left( \frac{x^{2}}{y} \right) &= 
    \frac{2}{y} & - \frac{2x}{y^{2}} \\
    -\frac{2x}{y^{2}} & \frac{2x^{2}}{y^{3}}
