Walls and asymptotics for Bridgeland stability conditions on 3-folds [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
We consider Bridgeland stability conditions for three-folds conjectured by Bayer-Macr\`i-Toda in the case of Picard rank one. We study the differential geometry of numerical walls, characterizing when they are bounded, discussing possible intersections ...

On modulus inequality of the order $p$ for the inner dilatation

open access: yesМатематичні Студії, 2023
The article is devoted to mappings with bounded and finite distortion of planar domains. Our investigations are devoted to the connection between mappings of the Sobolev class and upper bounds for the distortion of the modulus of families of paths.

Isolated singularities of mappings with the inverse Poletsky inequality

open access: yesМатематичні Студії, 2021
The manuscript is devoted to the study of mappings with finite distortion, which have been actively studied recently. We consider mappings satisfying the inverse Poletsky inequality, which can have branch points.

On compact classes of solutions of Dirichlet problem in simply connected domains

open access: yesМатематичні Студії, 2023
The article is devoted to compactness of solutions of the Dirichlet problem for the Beltrami equation in some simply connected domain. In terms of prime ends, we have proved corresponding results for the case when the maximal dilatations of these ...

On boundary extension of one class of mappings in terms of prime ends

open access: yesМатематичні Студії, 2020
Here we consider the classes of mappings of metric spaces that distort the modulus of families of paths similarly to Poletsky inequality. For domains, which are not locally connected at the boundaries, we obtain results on the boundary extension of the ...

D-branes at Toric Singularities: Model Building, Yukawa Couplings and Flavour Physics [PDF]

open access: yes, 2010
We discuss general properties of D-brane model building at toric singularities. Using dimer techniques to obtain the gauge theory from the structure of the singularity, we extract results on the matter sector and superpotential of the corresponding gauge

Tropicalization of the moduli space of stable maps [PDF]

open access: yes, 2015
Let $X$ be an algebraic variety and let $S$ be a tropical variety associated to $X$. We study the tropicalization map from the moduli space of stable maps into $X$ to the moduli space of tropical curves in $S$.

Filtered screens and augmented Teichm\"uller space [PDF]

open access: yes, 2015
We study a new bordification of the decorated Teichm\"uller space for a multiply punctured surface F by a space of filtered screens on the surface that arises from a natural elaboration of earlier work of McShane-Penner.

QUASI-ISOMETRIC MAPPINGS AND THE p-MODULI OF PATH FAMILIES

open access: yesIssues of Analysis, 2016
In this article, we study a connection between quasiisometric mappings of n-dimensional domains and the p-moduli of path families. In particular, we obtain explicit (and sharp) estimates for the distortion of the p-moduli of path families under K-quasi-isometric mappings.

On prime end distortion estimates of mappings with the Poletsky condition in domains with the Poincar´e inequality

open access: yesМатематичні Студії
This article is devoted to the study of mappings with bounded and finite distortion defined in some domain of the Euclidean space. We consider mappings that satisfy some upper estimates for the distortion of the modulus of families of paths, where the ...
