Solution of generalized bisymmetry type equations without surjectivity assumptions

  • Gy. Maksa

Summary.

The solution of the rectangular \( m \times n \) generalized bisymmetry equation¶¶\( F\bigl(G_1(x_{11},\dots,x_{1n}),\dots,\ G_m(x_{m1},\dots,x_{mn})\bigr) \quad = \quad G\bigl(F_1(x_{11},\dots, x_{m1}),\dots, \ F_n(x_{1n},\dots,x_{mn}) \bigr) \)(A)¶is presented assuming that the functions F, G j, G and F i (j = 1, ... , m , i = 1, ... , n , m≥ 2, n≥ 2) are real valued and defined on the Cartesian product of real intervals, and they are continuous and strictly monotonic in each real variable. Equation (A) is reduced to some special bisymmetry type equations by using induction methods. No surjectivity assumptions are made.
