I am using the notation $\widetilde{\mathcal{F}_K}$ quite extensively in my paper. In each line where it appears, because the tilde makes the symbol a little higher than the other symbols, the line spacing between this line and the previous line is increased. This is both unaesthetic, and also probably wastes a space-worth of a few lines (I am limited in place). Is there any way to alleviate this?

Edit: Following TH's advice, this would be a better command to use:
\newcommand{\trel}{\mathrel{\mathsurround=0pt \mbox{\raisebox{1.2pt}{\tiny \textbf{\textbar }}$\rhd$}}}
(I decided to explicitly say \mathsurround=0pt rather than just calling \m@th because that way, if Mike wants to paste this into the top of his document, he won't have to call \makeatletter)
Original: I don't know what built-in symbols would correspond to the one you're describing, but if you're just trying to get something done you could use this:
\newcommand{\trel}{\mbox{\raisebox{1.2pt}{\tiny \bf \textbar }$\rhd$}}
(and then use \trel every time you want to use this relation).
It's a huge hack, but, like I said, it might be enough to get you by.
y^{\prime\prime}
is the normal rendering for multiple primes, but it can be more easily entered by using the input
y''
In math mode ' has a special definition that a run of adjacent ' turns itself into ^{\prime...} with as many \prime in the superscript as there were ' in the original source.
However as others have said in comments your input looks suspiciously as if intended to be roman numerals
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$ y' \quad y'' \quad y''' $
$
y^\mathrm{\romannumeral 1} \quad
y^\mathrm{\romannumeral 2} \quad
y^\mathrm{\romannumeral 3} \quad
y^\mathrm{\romannumeral 4} \quad
y^\mathrm{\romannumeral 5}
$
\end{document}
Wikipedia suggests That the notation you want is primes for the first three, then Roman numerals so perhaps:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$ y' \quad y'' \quad y''' $
$
y^\textrm{\romannumeral 1} \quad
y^\textrm{\romannumeral 2} \quad
y^\textrm{\romannumeral 3} \quad
y^\textrm{\romannumeral 4} \quad
y^\textrm{\romannumeral 5}
$
\newcommand\lagrangeprime[1]{^{%
\ifcase#1 \or\prime\or\prime\prime\or\prime\prime\prime\else\mathrm{\romannumeral #1}\fi}}
$
y\lagrangeprime{1}\quad
y\lagrangeprime{2}\quad
y\lagrangeprime{3}\quad
y\lagrangeprime{4}\quad
y\lagrangeprime{5}
$
\end{document}

Try using
\smash(no package needed).Or
It will not rescale your symbol, but still fix those ugly varying line heights. Watch out for overlapping characters though!
