Abstract

Let p:XYp:X\to Y be an holomorphic surjective map between compact K\"ahler manifolds and let DD be an effective divisor on XX with generically simple normal crossings support and coefficients in (0,1)(0,1). Provided that the adjoint canonical bundle KXy+DyK_{X_y}+D_y of the generic fiber is ample, we show that the current obtained by glueing the fiberwise conic K\"ahler-Einstein metrics on the regular locus of the fibration is positive. Moreover, we prove that this current is bounded outside the divisor and that it extends to a positive current on XX.

Comments

24 pages; v2: there was a gap in section 5 which led us to weaken the statement on the regularity of the current outside D (bounded instead of smooth)
