Title: On Nontrivial Zeros of Riemann Zeta Function,
Abstract: Let {\Xi} be a function relating to the Riemann zeta function with . In this
paper, we construct a function containing and {\Xi} , and prove that satisfies
a nonadjoint boundary value problem to a nonsingular differential equation if
is any nontrivial zero of {\Xi} . Inspecting properties of and using known
results of nontrivial zeros of , we derive that nontrivial zeros of all have
real part equal to , which concludes that Riemann Hypothesis is true.
