Pointwise quasi-Newton methods update the coefficients of differential and integral operators in function spaces. This paper gives a general theory of such methods and unifies it with the theory of Broyden's method in Hilbert space. In particular, a new superlinearly convergent method is introduced for elliptic boundary value problems.
