Here are two solutions, one using the \mathrlap
command, from mathtools
, the other with a plain align*
environment and an array
. Also replaced \hat
with widehat
, which fits better the size of uppercase Q:
\documentclass{article}%
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{mathtools}
\begin{document}
\begin{alignat*}{2}
&\mathcal{F}^N(t) \subset {}&&\sigma \{Q_0^N(0), \widehat{Q}_1^N(0), \widehat{Q}_2^N(0)\} \vee \sigma \{A^N(s), 0 \leq s \leq t\}\\
& &&\vee \sigma\{S_{12}^l(s),S_{20}^l,0 \leq s \leq t, l \geq 1\}\\
& &&\vee \mathcal{N},\\
&\mathrlap{(Q_0^N(0), \widehat{Q}_1^N(0),\widehat{Q}_2^N(0)),} && \\
&A^N, && \\
&\mathrlap{S_{12}^l, S_{20}^l, l \geq 1 }
\end{alignat*}
\begin{align*}
&\mathcal{F}^N(t) \subset {}\begin{array}[t]{@{}l}\sigma \{Q_0^N(0), \widehat{Q}_1^N(0), \widehat{Q}_2^N(0)\} \vee \sigma \{A^N(s), 0 \leq s \leq t\}\\
\vee \sigma\{S_{12}^l(s),S_{20}^l,0 \leq s \leq t, l \geq 1\}\\
\vee \mathcal{N},
\end{array}\\
& (Q_0^N(0), \widehat{Q}_1^N(0),\widehat{Q}_2^N(0)),\\
& A^N, \\
& S_{12}^l, S_{20}^l, l \geq 1
\end{align*}
\end{document}
