Identities for sums of floor and ceiling functions of rational numbers


Atiratch Laoharenooa,*, Chanatip Sujsuntinukulb

 
ABSTRACT:     Research into sums involving floor or ceiling functions has been a popular focus in number theory. This paper investigates formulas for sums of the type Pn k=1 F € pk q Š , where F represents either the floor or ceiling function, and p, q are coprime integers. Generalizing from Palatsang et al?s work in 2021, we could derive explicit simp
