SUMMARY

Let H, K be unitary spaces. The second way of generalization of the orthogonality equation in Hilbert spaces H, K is to look for the solutions of_(1.3) hf (x)|g(y)i=hx|yi, x, y ∈ H, where f, g: H → K are unknown functions. Instead of taking two different functions on the left side of_(1.3), the authors change only the right side . . .
