Tamsayıların yarı-grupları üzerindeki genelleşmiş asal sayı teoremi ve Möbius fonksiyonu

In this study, we first prove the classical Prime Number Theorem whichgives an estimate on the number of primes not exceeding x where xis a given real number.Then, in the third chapter we prove the Wiener-Ikehara Tauberian Theoremand as a result of this theorem, we deduce the Prime Number Theorem just from the non-vanishingof the Riemann Zeta function on the line Re(s)=1.In chapter four, we prove Beurling's Generalized Prime Number Theoremon semi-groups of integers and we investigate the boundary condition of this theorem.Also, we consider the partial sums of the Mobius function over such semi-groupsand we show the difference between the Generalized Prime Number Theorem andthe partial sums of the Mobius function over semi-groups.Based on this difference, in the last part (which is a joint work withmy supervisor Assoc. Prof. Emre Alkan) we give quantitative estimates on partial sums of theMobius function over semi-groups that are also in a given arithmetic progression.Lastly, we apply our results to the fractions.
