Create a line break in a subscript-position term

My code is



documentclassarticle
usepackageamssymb,bm
beginequation
nabla_theta bmJ(theta) =
mathbbE_s sim T^bmpi, a sim bmpi_theta
[nabla_theta log bmpi(a | s ) cdot Q(s, a) ],
endequation

enddocument


And I want to break s sim T^bmpi, a sim bmpi_theta into two lines, not put it under mathbbE. 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.

documentclassarticle
usepackageamsmath % for 'DeclareMathOperator' and 'substack' macros
usepackageamssymb % for 'mathbb' macro
usepackagebm % for 'bm' macro
DeclareMathOperatorEmathbbE % define expectations operator
begindocument

beginequation
nabla_!theta bmJ(theta) =
E_substacks sim T^bmpi\ a sim bmpi_theta
[nabla_!theta logbmpi(amid s ) cdot Q(s,a) ]
endequation
enddocument
