ABC Conjecture and Riemann Hypothesis [PDF]

, 2004
In this paper, we consider two great unproven problems in mathematics in the language of inequalities; ABC conjecture and Riemann hypothesis. It is shown that the Riemann hypothesis is true in some initial cases.

Approximation of the Stieltjes Integral and Applications in Numerical Integration [PDF]

, 2003
Some inequalities for the Stieltjes integral and applications in numerical integration are given. The Stieltjes integral is approximated by the product of the divided difference of the integrator and the Lebesgue integral of the integrand.
