[Stabilité des faisceaux tangent logarithmiques équivariants sur les variétés toriques de rang de Picard deux]
Pour une paire logarithmique équivariante où est une variété torique normale et un diviseur de Weil réduit, nous étudions la stabilité au sens de la pente du faisceau tangent logarithmique . Nous donnons une description complète des diviseurs réduits et polarisations sur tels que le faisceau tangent logarithmique est (semi)stable par rapport à lorsque est une variété torique lisse de rang de Picard un ou deux.
For an equivariant log pair where is a normal toric variety and a reduced Weil divisor, we study slope-stability of the logarithmic tangent sheaf . We give a complete description of divisors and polarizations such that is (semi)stable with respect to when has a Picard rank one or two.
