Konstancja Bobecka, Jacek Wesołowski Annales Polonici Mathematici 82 (2003), 1-7 MSC: 39B52, 15A15, 39B22. DOI: 10.4064/ap82-1-1

Streszczenie

We solve the multiplicative Cauchy equation for real functions of symmetric positive definite matrices under the differentiability restriction. The specialty of the problem lies in the symmetry of the multiplication.
