I would like to join the mathgroup list, please. The list was kind 
enough to solve a problem I had recently.

I also have another urgent, and probably trivial (once you know how) 

I have an equation


I find the solution xm=x->g[y] which maximises f[x,y] for any y

I now want to define this 'maximised' function of y only fy[y]

I've tried:


but this doesn't seem to recognise that I want the y s from xm to 
'match' the y_ on the LHS.

I'm also unclear as to whether I want  :=  or  =  in the above line.

Thanks in anticipation
