Numerical treatment for time fractional order phytoplankton-toxic phytoplankton-zooplankton system

open access: yesAIMS Mathematics
The study of time-fractional problems with derivatives in terms of Caputo is a recent area of study in biological models. In this article, fractional differential equations with phytoplankton-toxic phytoplankton-zooplankton (PTPZ) system were solved ...

On stability estimations without any conditions of symmetry

open access: yesLietuvos Matematikos Rinkinys, 2023
Let X, X1, X2, ..., Xn be i.i.d. random variables. B. Ramachandran and C.R. Rao have proved that if distributions of sample mean ‾X = ‾X(n) = (X1 + ⋯ + Xn)/n and monomial X are coincident at least at two points n = j1 and n = j2 such that log j1/ log j2

Wall-crossing implies Brill-Noether applications of stability conditions on surfaces [PDF]

open access: yesAlgebraic Geometry, 2016
Over the last few years, wall-crossing for Bridgeland stability conditions has led to a large number of results in algebraic geometry, particular on birational geometry of moduli spaces. We illustrate some of the methods behind these result by reproving

Thermodynamic stability conditions for nonadditive composable entropies

open access: yes, 2003
The thermodynamic stability conditions (TSC) of nonadditive and composable entropies are discussed. Generally the concavity of a nonadditive entropy with respect to internal energy is not necessarily equivalent to the corresponding TSC.

Stability conditions on product threefolds of projective spaces and Abelian varieties [PDF]

open access: yes, 2017
In this paper, we prove the original Bogomolov–Gieseker type inequality conjecture for P1×S,P2×C and P1×P1×C , where S is an Abelian surface and C is an elliptic curve. In particular, there exist Bridgeland stability conditions on these threefolds.

STABILITY CONDITIONS IN SYMPLECTIC TOPOLOGY [PDF]

open access: yesInternational Congress of Mathematicans, 2017
We discuss potential (largely speculative) applications of Bridgeland's theory of stability conditions to symplectic mapping class groups.

A short proof of the deformation property of Bridgeland stability conditions [PDF]

open access: yesMathematische Annalen, 2016
The key result in the theory of Bridgeland stability conditions is the property that they form a complex manifold. This comes from the fact that given any small deformation of the central charge, there is a unique way to correspondingly deform the ...
