备注

将理想收敛应用到Banach空间研究中,利用序列的(弱)极大理想收敛来刻画局部(弱)紧集,作为推论也得到了(弱)紧集合的(弱)极大理想收敛刻画.

This paper applies ideal convergence to the research of Banach spaces.Such an application characterizes locally(weakly)compact sets by using the(weakly)maximally ideal convergence of the sequence.Consequently,we can also get the characterization of(weakly)compact sets via(weakly)maximally ideal convergence.
