Title: From random harmonic rational function to gravitational lensing effect.
The analysis on harmonic rational function has been used on studying gravitational lensing effect. With additional randomness brought into this system, we set up a formula for the expected number of images under the effect. The expectation is evaluated by a representation of absolute function, which is of independent interests. Some corollaries following this representation are also introduced.
