Hi. When I enter a long chain of equalities in LyX, the vertical spacing in the PDF changes dramatically. Are there any packages I can include that will not alter the vertical spacing of the text?
@TheSubstitute If I were to make a guess: Document --> Settings --> LaTeX preamble, add \allowdisplaybreaks. If that doesn't help, try with \raggedbottom instead. However as I don't know anything at all about how your document is set up, there's no guarantee any of them will do anything.
@TorbjørnT. \raggedbottom works. Now there's a large space before the chain since it starts on the following page. Is there a way to allow some of the chain to appear on both pages, or should I use two separate chains?
@TheSubstitute So you have several of those in a row? That's not the right way, use gather (or align, if you want to align the equals sign), Insert --> Math --> AMS gather Environment. Ctrl + enter to add a line break in those. Then add \allowdisplaybreaks to the preamble.
@TheSubstitute It depends a little bit what you're after. For a series of equations with no alignment, gather is best. If you want alignment, then align, as mentioned. If you have one very long equation that should be split over several lines, then multline might be best. If you want a single equation number for a whole group of equations, then use a normal equation environment (so same as for a single numbered equation), and add a split, aligned or gathered environment within that.

@JosephWright need to update that alias file to match what I think I understood from Hans reply that a couple of those pdfvariable will be removed (and so presumably will generate an error) incidentally unlike a tex csname there doesn't seem to be a way to tell if a pdfvariable thing is defined (other than checking luatexversion, and the manual) \pdfvariable zzzzz is an error.
@PauloCereda Usually I throw books after flys to kill them, but I am inclined to throw books after other animals, starting right way in the alphabet with .... ducks ... (my today's alphabet starts with D:-P)
@egreg ah I see what you mean, but that's ensuring that there is a space token after the \pagebreak not putting one before (although the space hacks mean that is the same thing, i agree)
I have this figure.1 in pdf format. The micro symbol in the y-axis label is fine in it but when i import it to latex to insert in my paper. The micro symbol changes to some kind of alpha symbol. Don't know why it is happening. Thank you
@ChristianHupfer yes not managed to do that yet so it's quite hard for me to change parity (and annoying when some vim user downvotes me on a day that I'm not rep capped and changes it)
If I use
\renewcommand{\textdexiakeraia}{}
I get no apostrophe (properly, number sign) in second level enumerated lists. The symbol for 6 is “stigma” (U+03DB); if you want to output the combination στ instead of ϛ, you can redefine \textstigma:
\renewcommand{\textstigma}{\textsigma\texttau}
...
But there have to be three columns, the notaion, the description and and which page it appears for the first time. How do we get these three columns? @egreg
