本文证明了Oeljeklaus-Toma流形X(K,U),其中K是签名(s,t)的数域,使得且不允许局部共形Kähler度量.结合Dubickas(N Y J Math 20:257-274,2014)和Oeljeklaus和Toma(Ann Inst Fourier Grenoble 55(1):161-171,2005)的早期结果,这完全解决了Oeljeklaus-Toma流形上局部共形Kähler度量的存在性问题。
We show that Oeljeklaus–Toma manifoldsX(K,U) whereKis a number field of signature (s,t) such thatandadmit no locally conformally Kähler metric. Combined with the earlier results by Dubickas (N Y J Math 20:257–274, 2014) and Oeljeklaus and Toma (Ann Inst Fourier Grenoble 55(1):161–171, 2005) this completely solves the problem of existence of locally conformally Kähler metrics on Oeljeklaus–Toma manifolds.
