ln (r) is the standard natural logarithm of the real number r. Arg (z) is the principal value of the arg function; its value is restricted to (−π, π]. It can be computed using Arg (x + iy) = atan2 (y, x). Log (z) is the principal value of the complex logarithm function and has imaginary part in the range (−π, π].
Closed-form expression. In mathematics, an expression or equation is in closed form if it is formed with constants, variables and a finite set of basic functions connected by arithmetic operations (+, −, ×, /, and integer powers) and function composition. Commonly, the allowed functions are n th root, exponential function, logarithm, and ...

Branch point. In the mathematical field of complex analysis, a branch point of a multivalued function is a point such that if the function is -valued (has values) at that point, all of its neighborhoods contain a point that has more than values. [1] Multi-valued functions are rigorously studied using Riemann surfaces, and the formal definition ...
