I want to display a curvy L n°1:

(An application is found here as well as this other question.)

However, when I enter the code

documentclass[a4paper, 12pt]{book}

usepackage{amssymb}

usepackage{amsmath}

usepackage{mathtools}

usepackage[utf8]{inputenc}

usepackage{geometry}

usepackage{url}

usepackage{framed}

usepackage{setspace}

usepackage{mathptmx}

usepackage{multirow}

usepackage{listings}

usepackage{xcolor}

usepackage{framed}



begin{document}

setlength{parindent}{0cm}

renewcommand{baselinestretch}{0.5}



$mathcal{L}$



end{document}

I get curvy L n°2:

How can I print the curvy L n°1?

If you adding the two rows

usepackage{calrsfs}

DeclareMathAlphabet{pazocal}{OMS}{zplm}{m}{n}

it is possibile, in the same file .tex, to use the both curvy option. I have removed usepackage{amsmath} with usepackage{mathtools} because loading mathtools, you will have both packages loaded and you do not need to usepackage{amsmath} in your preamble.

documentclass[a4paper, 12pt]{book}

usepackage{amssymb}

usepackage{mathtools}

usepackage[utf8]{inputenc}

usepackage{geometry}

usepackage{url}

usepackage{framed}

usepackage{setspace}

usepackage{mathptmx}

usepackage{multirow}

usepackage{listings}

usepackage{xcolor}

usepackage{framed}



usepackage{calrsfs}%%%%%%%%%%<------add

DeclareMathAlphabet{pazocal}{OMS}{zplm}{m}{n}%%%%%%%%%%<------add



begin{document}

setlength{parindent}{0cm}

renewcommand{baselinestretch}{0.5}



$mathcal{L}, pazocal{L}$



end{document}

Comment usepackage{mathptmx}.

Read page 5 in documentation of mathptmx. It says that the fonts for mathcal symbols will be changed.
