tex2lyx does not help in this case. The reason is the non-standard command \textoverset which is not supported by LyX. Form your file it seems that \textoverset takes two text arguments (the style files are not readable): \textoverset{${\mathchar"0362}$'}{$\sigma$}=\frac{1}{T} rewrite that as \overset{{\mathchar"0362}'}{\sigma}=\frac{1}{T} and everything should work.
