This Fellowship proposal in theoretical mathematics aims to solve three major open problems in wave propagation. These are the long-time behaviour of nonlinear waves, including the behaviour and interaction of solitary waves; the propagation of waves in rough media; and the small-scale behaviour of interacting waves under the assumption of chaotic ray dynamics. The research aims to analyse wave equations that model problems in optical media and waveguides, medical and seismic imaging, and nano-electronic devices. Outcomes and benefits are expected in new mathematical theory, Australian research capability, better algorithms for numerically computing waves, and technological advances in communications, medical imaging, and seismic imaging.

本奖学金计划旨在解决波传播中的三个主要开放问题。这些是非线性波的长期行为，包括孤立波的行为和相互作用;粗糙介质中的波的传播;以及在混沌射线动力学假设下相互作用波的小尺度行为。该研究旨在分析模拟光学介质和波导，医学和地震成像以及纳米电子器件问题的波动方程。预计在新的数学理论、澳大利亚的研究能力、数值计算波浪的更好算法以及通信、医学成像和地震成像方面的技术进步方面将产生成果和效益。
