摘要：

We consider the sensitivity of the matrix equations which arise when solving boundary integral equations of negative order, specifically in case of the typical example of the operator with logarithmic kernel. The sensitivity is expressed using condition numbers and it turns out that the local condition number is a very good indicator, in contrast to the ordinary condition number, traditionally used.
