While not explicitly stated, the following link enunciates difference- and differential operators that yield generalized Fibonacci sequences and functions with extensions to the complex domain, and addresses an arsenal of open questions in mathematics, such as generalized Riemann Zeta functions, Gamma- and Polygamma functions, with wast applications to both mathematics and physics:
''This volume represents the first attempt to compile a definitive history and authoritative analysis of these famous integer sequences, complete with a wealth of exciting applications, enlightening examples, and fun exercises that offer numerous opportunities for exploration and experimentation.''
