Computing the maps on ECH of prequantization bundles
Guanheng Chen
The purpose of this paper is to study the -module structure of the embedded contact homology of a class of prequantization circle bundles over closed symplectic surfaces. We ass…

On aspherical symplectic fillings with finite capacities of the prequantization bundles
Guanheng Chen
A prequantization bundle is a negative circle bundle over a symplectic surface together with a contact form induced by a S1-invariant connection. Given a symplectically aspherical…

An alternative definition of cobordism map of ECH
Guanheng Chen
In this article, we reformulate the cobordism map of embedded contact homology, which is induced by exact symplectic cobordism and defined as direct limit of homomorphisms called f…
