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?

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.

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}
