KW - Double layer potential equation, Nyström method, stability, critical angles.
AB - <p style="text-align: justify;">The Nyström method for double layer potential equations on simple closed
piecewise smooth contours is stable if and only if certain operators associated with the
opening angles of the corners are invertible. Numerical experiments show that there are
opening angles which cause the instability of the method.</p>
