  • Welcome to TeX.SX. Are you facing problem in putting them in two columns ? If so, it would be better to give a minimal working example of what you have tried so far.

  • minipage/multicol can create columns. And enumerate can do the numbering.

Here's a solution that uses the multicol package and a bespoke enumerate-like environment called myenum.



enter image description here



documentclass{article}
usepackage{enumitem}
newlist{myenum}{enumerate}{2}
setlist[myenum,1]{label=(alph*)}
setlist[myenum,2]{label=(roman*)}
usepackage{multicol}

begin{document}
begin{multicols}{2}
begin{myenum}
item $a>0$ and $age b$
begin{myenum}
item $Mage Xa$
item $Ma<Ya$
end{myenum}
item $b>0$ and $bge a$
begin{myenum}
item $Mbge Xb$
item $Mb<Yb$
end{myenum}
end{myenum}
end{multicols}
end{document}

An array with nested array will do:



documentclass{article}
usepackage{amsmath,mathtools}

DeclarePairedDelimiter{norm}{lVert}{rVert}

begin{document}

[
renewcommand{arraystretch}{1.2}
begin{array}{
@{}
l % label a
l % condition
@{hspace{6em}}
l % label b
l % condition
@{}
}
text{(a)} & norm{n_2}>0text{ and }norm{n_2}genorm{n_1} &
text{(b)} & norm{n_1}>0text{ and }norm{n_1}genorm{n_2} \
& begin{array}[t]{@{}ll@{}}
text{(i)} & norm{M_a n_2} ge tilde{kappa}norm{n_2}, \
text{(ii)} & norm{M_a n_2} < tilde{kappa}norm{n_2},
end{array}
&& begin{array}[t]{@{}ll@{}}
text{(i)} & norm{M_b n_1} ge tilde{kappa}norm{n_1}, \
text{(ii)} & norm{M_b n_1} < tilde{kappa}norm{n_1},
