| contents | The minimal log discrepancy is an invariant of singularities that plays an important role in the birational classification of algebraic varieties. Shokurov conjectured that the minimal log discrepancy can always be bounded from above in terms of the dimension of the variety. We prove this conjecture for general arrangement varieties, a particular class of T-varieties, adding to previous results on this conjecture which include threefolds, toric varieties, and local complete intersection varieties. |
