13:00 Lecture 1: Introduction to gravitational-wave science - Gabriel Luz Almeida (Shing-Tung Yau center, Southeast University)
Lecture 1: Introduction to gravitational-wave science
- Gabriel Luz Almeida (Shing-Tung Yau center, Southeast University)
13:00 - 14:15
Room: 逸夫建筑馆1502 We begin our journey with a broad overview of the science of Gravitational Waves (GWs). In this lecture, we will address fundamental questions such as, "What are gravitational waves?" and "What astrophysical events in the Universe can produce them?" We will also review the key discoveries of the past decade, following the first direct detection of GWs. This first lecture begins with a brief overview of the limitations of Newtonian gravity and its successor, Einstein's General Theory of Relativity. We then introduce the astrophysical sources of gravitational waves and trace the key historical developments leading to their discovery.

14:30 - 16:00
Room: 逸夫建筑馆1502 In this second lecture, we introduce the basic principles of gravitational wave detection, the characteristic waveforms produced by compact binary systems, and their important physical properties. We conclude the lecture with a discussion on the future prospects of Gravitational-Wave Astronomy and its potential to revolutionize our understanding of the cosmos.

13:00 Lecture 15: Angular momentum for gravitational waves - Hongbin Wang (Southeast university)
Lecture 15: Angular momentum for gravitational waves
- Hongbin Wang (Southeast university)
13:00 - 14:15
Room: 1502 In this lecture, we derived the angular momentum expression for gravitational waves from the Noether's theorem, by the symmetry of the action under rotations in three dimensions.
14:30 Lecture 16: Why spin-2 - Hongbin Wang (Southeast university)
Lecture 16: Why spin-2
- Hongbin Wang (Southeast university)
14:30 - 02:30
Room: 1502 In this lecture, we talked about why the gravitational field is the spin-2 fields. We examine different cases, from spin-0, spin-1 and spin more than 3. We found all of these cases except spin-2 are ruled out by some physical prediction contradictory to the facts.

13:00 Lecture 17: The Pauli-Fierz action - Hongbin Wang (Southeast university)
Lecture 17: The Pauli-Fierz action
- Hongbin Wang (Southeast university)
13:00 - 14:00
Room: 1502 In this lecture, we derived the Pauli-Fierz action, which is gauge-invariant and leads to the correct equation for linear order of gravitional field.
14:00 Lecture 18: The propagator - Hongbin Wang (Southeast university)
Lecture 18: The propagator
- Hongbin Wang (Southeast university)
14:00 - 15:00
Room: 1502 From the action leading to the linear equation of motion, we derived the propagator of gravitons in De Donder gauge. From the propagator we derived the expression of the gravitional interaction between two static point particles, which showed the consistency with Newton's gravity.

13:00 Lecture 19: Higher-order terms - Hongbin Wang (Southeast university)
Lecture 19: Higher-order terms
- Hongbin Wang (Southeast university)
13:00 - 14:00
Room: 1502 In this lecture, we explained the nonlinearity of gravity, and how construct higher-order terms in the action. From the dimensions, we saw how to determine the higher-order interacting terms in the action.
14:00 Lecture 20: GR as the effective theory - Hongbin Wang (Southeast university)
Lecture 20: GR as the effective theory
- Hongbin Wang (Southeast university)
14:00 - 15:00
Room: 1502 In the low-energy case, we saw we need only consider the leading terms in the expansion, from which point of view we explained the general relativity as a totally adequate low-energy field theory.

13:00 Lecture 21: The theory of massive gravitons - Hongbin Wang (Southeast university)
Lecture 21: The theory of massive gravitons
- Hongbin Wang (Southeast university)
13:00 - 14:00
Room: 1502 In this lecture, we considered the theory of massive gravitons. From some basic observations, we could determine the range of mass of gravitons.
14:00 Lecture 22: The problems in theory of massive gravitons - Hongbin Wang (Southeast university)
Lecture 22: The problems in theory of massive gravitons
- Hongbin Wang (Southeast university)
14:00 - 15:00
Room: 1502 By analogy with the massive electromagnetic field, we considered the massive gravitational field, deriving the propagators of massive gravitons. From some contradiction, we haven't established a "correct" theory of massive gravitons.
