We introduce a neural network inspired by Google's Inception model to compute the Hodge number $h^{1,1}$ of complete intersection Calabi-Yau (CICY) 3-folds. This architecture improves largely accuracy predictions over existing results, giving already 97% with just 30% data for training. Moreover, climbs 99% when using 80% proves that networks are valuable resource study geometric aspects in bot...
We show that an algebraic immediate valuation ring extension of characteristic $$p>0$$ is a filtered union complete intersection algebras finite type.
in 1970, menegazzo [gruppi nei quali ogni sottogruppo e intersezione di sottogruppi massimali, atti accad. naz. lincei rend. cl. sci. fis. mat. natur. 48 (1970), 559--562.] gave a complete description of the structure of soluble $im$-groups, i.e., groups in which every subgroup can be obtained as intersection of maximal subgroups. a group $g$ is said to have the $fm$...
We prove the almost complete intersection case of the Lex-Plus-Powers Conjecture on graded Betti numbers. We show that the resolution of a lex-plus-powers almost complete intersection provides an upper bound for the graded Betti numbers of any other ideal with regular sequence in the same degrees and the same Hilbert function. A key ingredient is finding an explicit comparison map between two K...
Working over the complex numbers, we study curves lying in a complete intersection K3 surface contained in a (nodal) complete intersection Calabi-Yau threefold. Under certain generality assumptions, we show that the linear system of curves in the surface is a connected componend of the the Hilbert scheme of the threefold. In the case of genus one, we deduce the existence of infinitesimally rigi...
