摘要：
We work out normal forms for quasi -elliptic Enriques surfaces and give several applications. These include torsors and numerically trivial automorphisms, but our main application is the completion of the classi fi cation of Enriques surfaces with fi nite automorphism groups started by Kond & oacute;, Nikulin, Martin and Katsura-Kond & oacute;-Martin.
