• Welcome! Which symbol? That is, are these 2 symbols, a \delta with something on top and another \cancel\delta with something below, or 4 symbols? Please see also detexify. – marmot Nov 27 '17 at 3:11

This is just to give you an idea to deal with such thing:

\documentclass{article}
\usepackage{amsmath}
\usepackage{cancel}
\begin{document}
$\overset{\wedge\!\!\wedge}{\delta}$

$\underset{\vee\!\!\vee}{\cancel{\delta}}$
\end{document}
