We show that the computational effort for the numerical solution of fermionic
quantum systems, occurring e.g., in quantum chemistry, solid state physics,
field theory in principle grows with less than the square of the particle
number for problems stated in one space dimension and with less than the cube
of the particle number for problems stated in three space dimensions. This is
proven by representation of effective algorithms for fermion systems in the
framework of the Feynman Path Integral.
