The general potential of power-law inflation is as $ V(\phi)\propto \phi^{n}$ with scalar field $\phi$. The behavior of inflation is often known aspower-law expansion like $S(\eta)\propto \eta^{1+\beta}$ with $1+\beta<0$. Inthis paper, the theoretical spectra of relic gravitational waves are comparedwith the measured strain sensitivity of Advanced LIGO and VIRGO, correspondingto the latest detected events of gravitational waves. The results show tightconstraints on $\beta$ and $n$. Also, the obtained constraints indicate thatspecial types of the potential of inflation, prototype, and KKLTI models, whichare originated from string theory, are more suitable than other models. Ouranalysis shows that there exist some more chances for the detection of relicgravitational waves.

Are latest detected events of gravitational waves in favor of some models of inflation based on string theory?
