# Having problem with mathcal

When I use mathcal{L} in texlive the output is not curvy L (Lagrange L) but another L. What should I do? Best

• Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. Jul 30 '19 at 16:32
• In addition to albert's remark, please add an image of the output you are seeing. Jul 30 '19 at 16:35
• You may change the font of \mathcal{L} with either unicode-math or mathalpha. Jul 30 '19 at 17:36
• Does the "curvy L" in this answer to the posting Looking for upright calligraphic L with little loop on top suit your needs? Or does the curvy L have to be more slanted to the right, i.e., less upright? Please advise.

• Do take a look at pp. 6-8 of the user guide of the mathalfa package -- type texdoc mathalfa in a command prompt to start the pdf viewer of the user guide -- for lots and lots of possibilities for a "script" L character.
