Stability Condition of Methane Hydrate in Fine-Grained Sediment

open access: yesJournal of Marine Science and Engineering, 2023
Stability condition is of critical importance for methane hydrate exploitation, transportation, and reserves. This study measured the stability conditions of methane hydrate in fine-grained sediment with different dry densities (ρd = 1.40, 1.50 and 1.60 ...

Stability conditions for polarised varieties

open access: yesForum of Mathematics, Sigma, 2023
We introduce an analogue of Bridgeland’s stability conditions for polarised varieties. Much as Bridgeland stability is modelled on slope stability of coherent sheaves, our notion of Z-stability is modelled on the notion of K-stability of polarised ...

Stability conditions and moduli spaces for Kuznetsov components of Gushel–Mukai varieties [PDF]

open access: yesGeometry & Topology, 2019
We prove the existence of Bridgeland stability conditions on the Kuznetsov components of Gushel-Mukai varieties, and describe the structure of moduli spaces of Bridgeland semistable objects in these categories in the even-dimensional case.

An eigenvalue problem for the differential operator with an integral condition

open access: yesLietuvos Matematikos Rinkinys, 2012
We analyze solution of a two-dimensional parabolic equation with a nonlocal integral condition by a locally one-dimensional method. The main aim of the paper is to deduce stability conditions of a system of one-dimensional equations with one integral ...

Stability conditions on product varieties [PDF]

open access: yesJournal für die Reine und Angewandte Mathematik, 2019
Given a stability condition on a smooth projective variety X, we construct a family of stability conditions on X × C {X\times C} , where C is a smooth projective curve. In particular, this gives the existence of stability conditions on arbitrary products

Stability conditions for 3-fold flops [PDF]

open access: yesDuke mathematical journal, 2019
Let $f\colon X\to\mathrm{Spec}\, R$ be a 3-fold flopping contraction, where $X$ has at worst Gorenstein terminal singularities and $R$ is complete local.
