On the smoothness of gap boundaries for generalized Harper operators

Gheorghe Nenciu

摘要:

将Harper算子谱的集合论连续性的结果推广到$L^{2}(\bZ^{2})$中的一类算子(广义Harper算子(GHO)).

英文摘要:

Results concerning set theoretic continuity properties of the spectrum of the Harper operator are extended to a large class (generalized Harper operators (GHO)) of operators in $L^{2}(\bZ^{2})$.
