Create a line break in a subscript-position term












2















My code is



documentclass{article}
usepackage{amssymb,bm}
begin{equation}
nabla_{theta} bm{J}(theta) =
mathbb{E}_{s sim T^{bm{pi}}, a sim bm{pi}_{theta}}
[nabla_{theta} log bm{pi}(a | s ) cdot Q(s, a) ],
end{equation}

end{document}


And I want to break {s sim T^{bm{pi}}, a sim bm{pi}_{theta}} into two lines, not put it under mathbb{E}. In the picture below, how to move the second part after the comma and stack under the first part?



enter image description here



How can I do that? Thank you in advance.

  • Off-topic: To "snug up" the nabla and theta symbols, consider writing nabla_{!theta}. The ! (negative thinspace) directive moves the subscript term to the left, i.e., closer to the nabla symbol.

I suggest you do two things:




  • Using DeclareMathOperator, make E a "math operator"


  • Use the substack macro to break the long line into two parts.



Both of these directives require loading of the amsmath package -- which you may be doing already.



enter image description here



documentclass{article}
usepackage{amsmath} % for 'DeclareMathOperator' and 'substack' macros
usepackage{amssymb} % for 'mathbb' macro
usepackage{bm} % for 'bm' macro
DeclareMathOperator{E}{mathbb{E}} % define expectations operator
begin{document}

begin{equation}
nabla_{!theta} bm{J}(theta) =
E_{substack{s sim T^{bm{pi}}\ a sim bm{pi}_{theta}}}
[nabla_{!theta} logbm{pi}(amid s ) cdot Q(s,a) ]
end{equation}
end{document}
