Query: Holographic Entropy and Calabi's Diastasis   The entanglement entropy for interfaces and junctions of two-dimensional CFTs
is evaluated on holographically dual half-BPS solutions to six-dimensional Type
4b supergravity with m anti-symmetric tensor supermultiplets. It is shown that
the moduli space for an N-junction solution projects to N points in the Kaehler
manifold SO(2,m)/( SO(2) x SO(m)). For N=2 the interface entropy is expressed
in terms of the central charge and Calabi's diastasis function on
SO(2,m)/(SO(2) x SO(m)), thereby lending support from holography to a proposal
of Bachas, Brunner, Douglas, and Rastelli. For N=3, the entanglement entropy
for a 3-junction decomposes into a sum of diastasis functions between pairs,
weighed by combinations of the three central charges, provided the flux charges
are all parallel to one another or, more generally, provided the space of flux
charges is orthogonal to the space of unattracted scalars. Under similar
assumptions for N>3, the entanglement entropy for the N-junction solves a
variational problem whose data consist of the N central charges, and the
diastasis function evaluated between pairs of N asymptotic AdS_3 x S^3 regions.
