Local Convergence for Multi-Step High Order Solvers under Weak Conditions

open access: yesMathematics, 2020
Our aim in this article is to suggest an extended local convergence study for a class of multi-step solvers for nonlinear equations valued in a Banach space.

Dynamics of Weak First Order Phase Transitions [PDF]

open access: yes, 1994
The dynamics of weak vs. strong first order phase transitions is investigated numerically for 2+1 dimensional scalar field models. It is argued that the change from a weak to a strong transition is itself a (second order) phase transition, with the order

The facial weak order and its lattice quotients [PDF]

open access: yes, 2016
We investigate a poset structure that extends the weak order on a finite Coxeter group $W$ to the set of all faces of the permutahedron of $W$. We call this order the facial weak order.

Tunable stripe order and weak superconductivity in the Moiré Hubbard model

open access: yesPhysical Review Research, 2022
The moiré Hubbard model describes correlations in certain homobilayer twisted transition metal dichalcogenides. Using exact diagonalization and density matrix renormalization group methods, we find magnetic Mott insulating and metallic phases which, upon

Extended Convergence for Two Sixth Order Methods under the Same Weak Conditions

open access: yesFoundations, 2023
High-convergence order iterative methods play a major role in scientific, computational and engineering mathematics, as they produce sequences that converge and thereby provide solutions to nonlinear equations.

DIRK Schemes with High Weak Stage Order

open access: yes, 2020
Runge-Kutta time-stepping methods in general suffer from order reduction: the observed order of convergence may be less than the formal order when applied to certain stiff problems.

Weak first-order superfluid--solid quantum phase transitions [PDF]

open access: yes, 2004
We study superfluid--solid zero-temperature transitions in two-dimensional lattice boson/spin models by Worm-Algorithm Monte Carlo simulations. We observe that such transitions are typically first-order with the exception of special high-symmetry points ...

An Investigation on Weak Concepts in Ordered Hyperstructures [PDF]

open access: yesSymmetry, 2021
The class of weak pseudoorders and left weak interior hyperideals in ordered hyperstructures is a generalization of pseudoorders and interior hyperideals. In this work, we study the concept of weak pseudoorders and left weak interior hyperideals in ordered hyperstructures and explore some results concerning the new defined concepts for ordered ...
