How to write a boldface italic in math mode when Zapf Chancery is used?

I used this code:

\documentclass{article}

\usepackage{amsmath}
\usepackage[latin9]{inputenc}
\usepackage{mathptmx}
\DeclareMathAlphabet{\mathpzc}{OT1}{pzc}{m}{it}

\begin{document}

    We define the following equation:
    \[\mathpzc{S} = \sum_{k=0}^n\dfrac{1}{k^3}.\]


    Now let $\mathbf{x}$ be the following vector:
    \[\mathbf{x}=[x_1, \ldots, x_n]^\mathsf{T}\]

\end{document}

But, the vector 'x' is not italic. It looks more like if it was \textbf{x}.

  • Use the bm package and \bm{x}. – Bernard Aug 03 '15 at 15:34

    You should consider to mark your vector by \vec{x}, see: http://tex.stackexchange.com/questions/258218/how-to-change-all-vec-to-bf/258286#258286 and http://tex.stackexchange.com/questions/248179/separate-content-from-formatting-i-e-just-type/254709#254709 – Ruben Aug 03 '15 at 16:18
  • There is no bold, is there? I don't have one. You can get faked bold e.g. with bm but that is always something of a compromise, of course. – cfr Aug 03 '15 at 17:05
