Stability of Equivariant Logarithmic Tangent Sheaves on Toric Varieties of Picard Rank Two

Abstract: 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 $\mathcal{T}{X}(- \log D)$. We give a complete description of divisors $D$ and polarizations $L$ such that $\mathcal{T}{X}(- \log D)$ is (semi)stable with respect to $L$ when $X$ has a Picard rank one or two.
