The method contributes to the solution of the problem that with traditional methods of character representation their shape and content are mutually underivable. The solution requires an innovative approach in rethinking on the very basic level of the character system. The two main contributions of the dissertation are: 1) Delta Number, an innovation of the numeral system, and 2) Rational Character, an innovation of the sign system.deinfo:eu-repo/semantics/openAccessmathematical semioticsquantitative digitdelta numberrational character620Dissertationurn:nbn:de:gbv:46-00106343-12
