我们证明了如果基本系统(即与半反正则丛相关联的线性系统,它在任何扭量空间上都是可用的)是束,则扭量空间的代数维数不可能是2。这意味着,如果上扭量空间的代数维数是2,那么基本系统要么是空的,要么是由单个成员组成的。代数维数为2的扭量空间的存在性问题是开放的。
We show that the algebraic dimension of a twistor space overcannot be two ifand the fundamental system (that is, the linear system associated to the half‐anti‐canonical bundle, which is available on any twistor space) is a pencil. This means that if the algebraic dimension of a twistor space on,, is two, then the fundamental system is either empty or consists of a single member. The existence problem for a twistor space onwith algebraic dimension two is open for.
