NettetHodge-Tate representations are stable under duality, tensor product, direct sum, and passage to submodules and quotients. Serre says this on p471 of Ouevres III (his article on algebraic groups associated to Hodge-Tate Galois representations). Moreover the category of Hodge-Tate representations is an abelian tensor category.

Nettet7. okt. 2024 · I need to assume that X and B are algebraic, compact and smooth. Then, the Hodge numbers of X coincide with the Hodge numbers of F × B. For see this, consider the Grothendieck ring of varieties K 0 ( Var / C). This is the ring generated by varieties over C, quotiented by the "scissor relation" [ X] = [ Y] + [ X ∖ Y] where Y ⊂ X is closed. Nettetasymmetry in Hodge numbers, H0(X; 1 X) = 0 while H (X;O X) = C. On the other hand, some other non-K ahler manifolds such as the Iwasawa manifolds do not have a p-adic analogue. The basic cohomological invariants of a compact complex manifold also exist in this setting.

The set of 4370 LG Hodge pairs we consider is a combination of the three classes listed, namely “untwisted models”, “abelian orbifolds” and “discrete torsion”.

NettetFor a K3 surface, the Hodge numbers hp;q(S) := dimHq(S; p S) are determined as follows: By de nition, we have h0;0 = h2;0 = h0;2 = h2;2 = 1. We have also determined above that h1;1 = 20, and all other Hodge numbers vanish by Hodge decomposition. So, the Hodge diamond looks as follows: 1 0 0 1 20 1 0 0 1 Next, let us give some examples. The Hodge number h p,q (X) means the dimension of the complex vector space H p.q (X). These are important invariants of a smooth complex projective variety; they do not change when the complex structure of X is varied continuously, and yet they are in general not topological invariants. Se mer In mathematics, Hodge theory, named after W. V. D. Hodge, is a method for studying the cohomology groups of a smooth manifold M using partial differential equations.
