Without her constant and unfailing … NettetA Lefschetz class on a smooth projective variety is an element of the Q-algebra generated by divisor classes. We show that it is possible to define Q-linear Tannakian categories of abelian motives using the Lefschetz classes as correspondences, and we compute the fundamental groups of the categories. As an application, we prove that the Hodge ... essential 10 super greens reviews

Nettet7. aug. 2024 · In this paper, we classify relatively minimal genus-$1$ holomorphic Lefschetz pencils up to smooth isomorphism. We first show that such a pencil is isomorphic to either the pencil on $\\mathbb{P}^1\\times \\mathbb{P}^1$ of bi-degree $(2,2)$ or a blow-up of the pencil on $\\mathbb{P}^2$ of degree $3$, provided that no … Nettet7. okt. 1972 · Dr. Lefschetz wrote over 100 papers, including 15 that were prepared in the last 20 years. His research helped pioneer the development of topology in the 1930's and the 1940's.
