Hello!Lowercase-lambdas are not shown in my Lyx-documents. Uppercase Deltas are shown. The Preset I use is thesis (chapter-1 or chapter-2, does not matter). I activated "Non-Tex-Fonts" in the Document-Options. If I don't do that, deltas aren't shown, either. I use LuaTex.
A minimal example is attached. I hope I provided all necessary information. Thanks in advance! Ph.
