Differentiable intrinsic functions of complex matrices
Introduction. Let 2X be a finite dimensional linear associative algebra with identity over the real or complex field 5F with basis el, * , er. A function F(x) with domain and range in 2r may be written as F(x) rej, where x= iei and '71i =(, 71, *.r), i 77 …
