论文摘要
让$ω$为真正的$ 4 $ -torus $ t^4 $的Kaehler形式。假设$ω$满足非理性条件，这可以通过$ω$的任意小扰动来实现。本说明表明，$（t^4，ω）$的单点符号爆炸的平稳符号映射类组是无限生成的。
Let $ω$ be a Kaehler form on the real $4$-torus $T^4$. Suppose that $ω$ satisfies an irrationality condition which can be achieved by an arbitrarily small perturbation of $ω$. This note shows that the smoothly trivial symplectic mapping class group of the one-point symplectic blowup of $(T^4,ω)$ is infinitely generated.
