Quick Question about Smooth Maps

  1. Oct 28, 2011 #1
    Hello everyone, I just had a quick question I was hoping somebody could answer.

    If [itex]f: M \times N \rightarrow P[/itex] is a smooth map, where [itex]M,N[/itex] and [itex]P[/itex] are smooth manifolds, then is it true for fixed [itex]m[/itex] that [itex]f_m : N \rightarrow P[/itex] is smooth, where [itex]f_m (n) = f(m,n)[/itex]?

    Any help would be appreciated.

    Of course, since the equivalent statement when M=R^m, N=R^n is true.
