Hello, this is Travor Liu. I am currently an undergraduate student studying Mathematics at University College London. I am glad to share my journey of discovery in number theory here.

My real name is Zihao Liu. You may contact me via zihao.liu.22 [at] ucl [dot] ac [dot] uk

My research interest lies in multiplicative number theory and sieve theory, and I am also constantly blogging about what I recently learned.
