The motive of a variety with cellular resolution of singularities
A complex variety $X$ admits a \emph{cellular resolution of singularities} if
there exists a resolution of singularities $\widetilde X\to X$ such that its
exceptional locus as well as $\widetilde X$ and the singular locus of $X$ admit
a cellular decomposition. We give a concrete description of the motive with
compact support of $X$ in terms of its Borel--Moore homology, under some mild
conditions. We give many examples, including rational projective curves and
toric varieties of dimension two and three.
