MAXIMAL NILPOTENT COMPLEX STRUCTURES [PDF]
Transformation Groups, 2022 Let the pair $(\mathfrak{g},J)$ be a nilpotent Lie algebra $\mathfrak{g}$ (NLA for short) endowed with a nilpotent complex structure $J$. In this paper, motivated by a question in the work of Cordero, Fernández, Gray and Ugarte, we prove that $2\leq ν(J) \leq 3$ for $(\mathfrak{g},J)$ when $ν(\mathfrak{g})=2$, where $ν(\mathfrak{g})$ is the step of ...

Higher Complex Structures [PDF]
International Mathematics Research Notices, 2019 Abstract We introduce and analyze a new geometric structure on topological surfaces generalizing the complex structure. To define this so-called higher complex structure, we use the punctual Hilbert scheme of the plane. The moduli space of higher complex structures is defined and is shown to be a generalization of the classical ...

Complex cellular structures [PDF]
Annals of Mathematics, 2019 We introduce the notion of a complex cell, a complexification of the cells/cylinders used in real tame geometry. For $ \in(0,1)$ and a complex cell $\mathcal{C}$ we define its holomorphic extension $\mathcal{C}\subset\mathcal{C}^ $, which is again a complex cell.

Polyharmonic Almost Complex Structures [PDF]
The Journal of Geometric Analysis, 2021 In this paper we consider the existence and regularity of weakly polyharmonic almost complex structures on a compact almost Hermitian manifold $M^{2m}$. Such objects satisfy the elliptic system weakly $[J, ^m J]=0$. We prove a very general regularity theorem for semilinear systems in critical dimensions (with \emph{critical growth nonlinearities ...

SnapShot: Mediator complex structure. [PDF]
Cell, 2022 The Mediator complex controls RNA polymerase II transcription genome-wide. In humans, Mediator consists of 26 subunits; furthermore, a four-subunit "Mediator kinase module" can reversibly associate with the complex. Mediator structure is generally conserved from yeast to humans, although the human complex is larger, more structurally disordered, and ...

Botulism in Cattle: A Case Report of an Outbreak in Sardinia (Italy)
Animals, 2023 Clostridium botulinum is the main causative agent of botulism in humans and animals. The ingestion of the botulinum neurotoxin, usually types C and D, has been shown to produce disease (neurological symptoms) in most botulism cases in cattle.
