          amsmath's cases is defined for this. The horizontal space between the bracket and the inside contents is very good.



          documentclass{article}
          usepackage{amsmath}
          begin{document}
          [
          mathrm{lev}_{a,b}(i,j)=begin{cases}
          max(i,j)&text{if $min(i,j)=0$,}\
          minbegin{cases}
          mathrm{lev}_{a,b}(i-1,j)+1\
          mathrm{lev}_{a,b}(i,j-1)+1\
          mathrm{lev}_{a,b}(i-1,j-1)+1_{(a_ine b_j)}
          end{cases} &text{otherwise.}
          end{cases}
          ]
          end{document}

          It seems to me that you are writing a document which uses lev() function quite often. In this case, you should define a new macro to avoid repetition



          documentclass{article}
          usepackage{amsmath}
          newcommand{lev}{mathrm{lev}}
          begin{document}
          [
          lev_{a,b}(i,j)=begin{cases}
          max(i,j)&text{if $min(i,j)=0$,}\
          minbegin{cases}
          lev_{a,b}(i-1,j)+1\
          lev_{a,b}(i,j-1)+1\
          lev_{a,b}(i-1,j-1)+1_{(a_ine b_j)}
          end{cases} &text{otherwise.}
          end{cases}
          ]
          end{document}

            newcommand{lev}[2]{mathrm{lev}_{a, thinspace b} (#1, thinspace #2)}



            Just type lev and you will get the function with two arguments to enter.

            newcommand{lev}[2]{mathrm{lev}_{a, thinspace b} (#1, thinspace #2)}
            begin{equation}
            lev{i}{j} = leftlbrace
            begin{array}{l l}
            max(i, thinspace j) & text{if~} min(i, thinspace j) =0,
            \
            min leftlbrace hspace{-1mm}
            begin{array}{l}
            lev{i-1}{j} + 1
            \
            addlinespace[0.5mm]
            lev{i}{j-1} + 1
            \
            addlinespace[0.5mm]
            lev{i-1}{j-1} + 1_{(a_{i} neq b_{j})}
            end{array}

            right. & text{otherwise}.
            end{array}
            right.

                        If you use the function lev a lot then it is a good idea to define it as follows



                        newcommand{lev}[2]{mathrm{lev}_{a, thinspace b} (#1, thinspace #2)}



                        Just type lev and you will get the function with two arguments to enter.
