Ключевые слова: Теория Дональдсона-Томаса, эквивариантный вертекс, М-теория. objectives: DT theory, equivariant vertex, M-theory Аннотация: K-theoretic Donaldson-Thomas counts of curves in toric and many related threefolds can be computed in terms of a certain canonical 3-valent tensor, the K-theoretic equivariant vertex. In the talk I will derive a formula for the vertex in the case when two out of three entr
