STABILITY OF EQUIVARIANT LOGARITHMIC TANGENT SHEAVES ON TORIC VARIETIES OF PICARD RANK TWO
Résumé
For an equivariant log pair (X, D) where X is a normal toric variety and D a reduced Weil divisor, we study slope-stability of the logarithmic tangent sheaf T_X(− log D). We give a complete description of divisors D and polarizations L such that T_X (− log D) is (semi)stable with respect to L when X has a Picard rank one or two.
