During 7th March to 10th March, the International Conference on PDEs, Geometric Analysis and Functional Inequalities was held in the University of Sydney, Australia. The aim of the conference is to demonstrate and strengthen connections between partial differential equations, geometry and functional inequalities. I was lucky to be among the more than 30 participants from all over the world, and benefited from the excellent talks.

One of the most enlightening talks was given by Neil Trudinger, who is a famous researcher in PDEs. He introduced the classical solutions of generated Jacobian equations and explained profound theories related to Monge-Ampere type equations in simple language, which impressed me most and encouraged me for my research. On the other hand, Neil is very amiable and humorous. As one of the authors of the excellent book, Elliptic Partial Differential Equations of Second Order, he answered our questions patiently and carefully during his talk. And during the Women in Mathematic Dinner on 7th March, Neil was asked a question “Neil, if you were God, which of course you are, and you could change one thing: what would it be?”. Amusingly, he replies: “Well, get rid of Trump!” What a lovely man!

Due to personal reasons, I came back to Wollongong by train every night during the conference, but I never missed the interesting and beautiful process because of the shared emails by Glen, one of the organisers in the University of Wollongong.

What an unforgettable memory!
