abstract = {<p style="text-align: justify;">This article deals with the efficient and accurate computation of the electrostatic forces between charged, spherical dielectric particles undergoing mutual polarisation. We use the spectral Galerkin boundary integral equation framework developed
by Lindgren et al. (J. Comput. Phys. 371 (2018): 712-731) and subsequently analysed
in two earlier contributions of the authors to propose a linear scaling in cost algorithm
for the computation of the approximate forces. We establish exponential convergence
of the method and derive error estimates for the approximate forces that do not explicitly depend on the number of dielectric particles $N$. Consequently, the proposed
method requires only&nbsp;$\mathcal{O}(N) $ operations to compute the electrostatic forces acting on $N$ dielectric particles up to any given and fixed relative error.</p>},
