Does any know how I can combine itemize and aligned (with argument [t]) -- or another multi-line mathematical environment -- in order to obtain a multi-line equation whose first line is aligned to the left and the remaining lines are aligned to the right?

I tried to illustrate what I would like to obtain in the picture below.

My current latex-code is the following:

documentclass[letterpaper]{article}

usepackage{amsthm}

usepackage{mathtools}

usepackage{bm}

begin{document}



$bm{f}^{cup}(B^1,B^2), bm{f}^{cap}(B^1,B^2) in mathcal{B}(Sigma_1cupSigma_2, wcdot w^{prime})$, respectively, where

begin{itemize}small

    item $begin{aligned}[t]

       ell(bm{f}^{cup}(B^1,B^2)) = {w^{prime}cdot(mathfrak{p}-1) + mathfrak{p}^{prime} colon mathfrak{p}inell(B_i),\

mathfrak{p}^{prime}inell(B_i)}text{;}

          end{aligned}$

    item $r(B_i^{*}) = {w^{prime}cdot(mathfrak{q}-1) + mathfrak{q}^{prime} colon mathfrak{q} in r(B_i), mahfrak{q}^{prime}in r(B_i)}$ ;

end{itemize}

end{document}

which results in something like the picture below.

Thanks!!

Is this what you want?

documentclass{article}

usepackage{amsmath,amsfonts}



begin{document}

begin{itemize}

item $begin{aligned}[t]

ell(mathbf{f}{^cup (B^1,B^2)})=lbrace w' cdot (mathfrak{p}-1)+mathfrak{p}') :& \

mathfrak{p}in ell(B_i), mathfrak{p}1in ell(B'_i)rbrace;

end{aligned}$

end{itemize}

end{document}

I think you want something like this. Remeber align(ed) require & to mark the alignment points. I took the opportunity to simplify a bit your code : typing ^{prime} isn't necessary, ' is enough.

documentclass[letterpaper]{article}

usepackage{amsthm}

$bm{f}^{cup}(B^1,B^2), bm{f}^{cap}(B^1,B^2) in mathcal{B}(Sigma_1cupSigma_2, wcdot w^{prime})$, respectively, where

begin{itemize}small

    item $begin{aligned}[t]

       ell(bm{f}^{cup}(B^1,B^2)) = {w'cdot(mathfrak{p}-1) & + mathfrak{p}' colon \

      & phantom{+}mathfrak{p}inell(B_i),mathfrak{p}'inell(B_i)}text{;}

          end{aligned}$

    item $r(B_i^{*}) = {w'cdot(mathfrak{q}-1) + mathfrak{q}' colon mathfrak{q} in r(B_i), mathfrak{q}'in r(B_i)}$ ;

end{itemize}
