formatting a long equation

[Nirmal Govind]

Hi.. how do I get a long equation in a display environment to split
itself into two lines or more as necessary.. attached is a lyx file with
one such long equation that I'd like to have split.. I tried \sloppy in
the preamble but it doesn't work.. probably cos the equation is in the
display mode?

Thanks,
nirmal
