AB - <p style="text-align: justify;">We present a new numerical method for solving two-dimensional Stokes
flow with deformable interfaces such as dynamics of suspended drops or bubbles.
The method is based on a boundary integral formulation for the interfacial velocity
and is spectrally accurate in space. We analyze the singular behavior of the integrals
(single-layer and double-layer integrals) appearing in the equations. The interfaces are
formulated in the tangent angle and arc-length coordinates and, to reduce the stiffness
of the evolution equation, the marker points are evenly distributed in arc-length by
choosing a proper tangential velocity along the interfaces. Examples of Stokes flow
with bubbles are provided to demonstrate the accuracy and effectiveness of the numerical
method.</p>
