If I remember right this is a bug in the luatex version that ships with texlive. Does
\def\Ustartmath{$} \def\Ustopmath {$}
The problem seems to be with \Umathquad\displaystyle not being said, which usually means he is loading a math font that has no math parameters. For lualatex this used to be some TTF version of CM fonts that are erroneously have similar file names (with different extension) to the TFM fonts so it gets loaded instead of the real CM fonts. On my Debian system, the were two versions, one bundled with LyX and one with some other latex fonts package.
it looks like that there are no math fonts available: [..] !define font : forced type tfm of eufm7 not found !define font : font with name eufm7 is not found !define font : forced type tfm of eufb7 not found !define font : font with name eufb7 is not found !math virtual : font LMMath7-Regular, no parameters set !math virtual : the mapping is incomplete for 'LMMath7-Regular' at 7pt !math virtual : font LMMath7-Regular, no parameters set !math virtual : font LMMath7-Regular, no parameters set !math virtual : font LMMath7-Regular, no parameters set !math virtual : font LMMath7-Regular, no parameters set !math virtual : font LMMath7-Regular, no parameters set [...] Herbert
