Abstract

As strong evidence for inflation, relic gravitational waves (RGW) have been extensively studied. Although they have not been detected yet, some constraints have been achieved by observations. Future experiments for RGW detection are mainly of two kinds: CMB experiments and laser interferometers. In this paper, we study these current constraints and the detective abilities of future experiments. We calculate the strength of RGW ?g(k) using two methods: the analytic method and the numerical method, by solving the inflationary flow equations. By the first method, we obtain a bound ?g<3.89
