This may be due to the type of question. I never used the svmono class and have no idea what it is or which packages it (in turn) requires. Also, as this is a LaTeX limitation, the LyX list is less likely to bring an adequate answer. I know that this is not you fault, but maybe it can explain you the nonresponsiveness. > Or, maybe there are better solutions? There are better solutions: there are a number of alternative font packages for Times-compatible maths. I recommend http://www.ctan.org/pkg/newtx (although I don't like its integral sign). A (German) survey can be found at http://milde.users.sourceforge.net/Matheschriften/matheschriften.html In LyX these packages could be specified in the user preamble. I don't know if there may be problems in use combined with svmono, if yes, please post a minimal example. > Someone suggested to use the isomath package, but this gives > a worse result, in my opinion, than the above solution, as for the > Serif / Times Roman fonts the bold form does not appear in pdf. Whiel isomath cannot solve the font problem if there is no font, I still recommend it for reasons obvious to any reader of the documentation ;-) Günter
