Multiplicative inversions involving real zero and neverending ascending infinity in the multispatial framework of paired dual reciprocal spaces

Jakub Czajko

World Scientific News > 2021 > 151 > 1-15

Inverses of complex numbers and of analytic functions are composites of mixed type for they are multiplicative inverses (i.e. reciprocals) of the modulus/magnitude combined with additive reverses of the argument/angle. Hence, the mixed inverses in the complex domain ℂ are not really reciprocals and therefore their lack of truly multiplicative reciprocity was a contributing reason that spurred the...
