.研究了Dirac算子与对称W1,∞ -势在截面曲率有界且直径在极限中损失一维的自旋流形的坍缩序列上的谱的行为.如果在极限空间N上存在诱导自旋或pin −结构,则存在收敛于N上一阶微分算子D的谱以及对称W1,∞ -势的本征值。在可定向极限空间N的情况下,D是N上的自旋狄拉克算子D N,如果极限空间的维数是偶数,如果极限空间的维数是奇数,则D = D N <$− D N。
. We study the behavior of the spectrum of the Dirac operator together with a symmetric W 1 , ∞ -potential on a collapsing sequence of spin manifolds with bounded sectional curvature and diameter losing one dimension in the limit. If there is an induced spin or pin − structure on the limit space N , then there are eigenvalues that converge to the spectrum of a first order differential operator D on N together with a symmetric W 1 , ∞ -potential. In the case of an orientable limit space N , D is the spin Dirac operator D N on N if the dimension of the limit space is even and if the dimension of the limit space is odd, then D = D N ⊕− D N .
