讲座内容：

It has been a half-decade since the first direct detection of gravitational waves, which signifies the coming of the era of the gravitational-wave astronomy and gravitational-wave cosmology. The increasing number of the detected gravitational-wave events has revealed the promising capability of constraining various aspects of cosmology. Interestingly, like the strong gravitational lensing of optical signals, GW lensing attracted many interests in the last decade. Though currently, we have not yet found any sufficient evidence for the GW lensing signal from the released LIGO data , the development of the methodology of applying GW lensing to cosmology still deserves many studies. In this talk, I will give a brief introduction of our recent works based on the DECi-hertz Interferometer Gravitational-wave Observatory (DECIGO)- a future Japanese space gravitational-wave antenna, focusing on the GW strong lensing and its extensive applications in cosmology, fundamental physics and astrophysics.
