一、题目:
The Absorbing Method and Hamiltonian Cycles
二、主讲人:

三、摘要:
The absorbing method, pioneered by Rödl, Ruciński and Szemerédi, has been a powerful tool in building spanning subgraphs. Roughly speaking, to build a spanning subgraph H of the host graph G, one usually sets aside a small absorbing structure A, which can turn an almost spanning subgraph to a spanning one.
This mini-course aims to introduce the absorbing method and its recent variants. Along the way we also give a quick survey with an emphasis on the comparison with the celebrated Blow-up Lemma.
