[Increase functions of the type dW/dt = k Wm/tp and their integrals (author's transl)]

Continuing systematical investigations into increase functions the type dW/dt = k Wm/tp is treated. This case yields 2 types of integrals or growth functions according to m = 1 and m greater than 1 respectively, both reaching adultness after infinite time. Approximation to the final value W = E can be quite different following the amount of m and p especially. Examples are given for comparing the growth function with that of Janoschek (1957) implying 3 parameters instead of four.
