Matrix-analytic methods for the analysis of stochastic fluid-fluid models
Stochastic Models, 2022 Stochastic fluid-fluid models (SFFMs) offer powerful modeling ability for a wide range of real-life systems of significance. The existing theoretical framework for this class of models is in terms of operator-analytic methods. For the first time, we establish matrix-analytic methods for the efficient analysis of SFFMs.

Zerofinding of analytic functions by structured matrix methods [PDF]
, 2016 We propose a fast and numerically robust algorithm based on structured numerical linear algebra technology for the computation of the zeros of an analytic function inside the unit circle in the complex plane. At the core of our method there are two matrix algorithms: (a) a fast reduction of a certain linearization of the zerofinding problem to a matrix

A comparison between analytic and numerical methods for modelling automotive dissipative silencers with mean flow [PDF]
, 2009 Identifying an appropriate method for modelling automotive dissipative silencers normally requires one to choose between analytic and numerical methods.

Information Anatomy of Stochastic Equilibria
Entropy, 2014 A stochastic nonlinear dynamical system generates information, as measured by its entropy rate. Some—the ephemeral information—is dissipated and some—the bound information—is actively stored and so affects future behavior.

Bootstrapping 2d ϕ 4 theory with Hamiltonian truncation data
Journal of High Energy Physics, 2022 We combine the methods of Hamiltonian Truncation and the recently proposed generalisation of the S-matrix bootstrap that includes local operators to determine the two-particle scattering amplitude and the two-particle form factor of the stress tensor at ...

Partial Differential Equations in Applied Mathematics, 2022 An analytic iteration sequence based on the extension of the BLUES (Beyond Linear Use of Equation Superposition) function method to partial differential equations (PDEs) with second-order time derivatives is studied. The original formulation of the BLUES

Improved iterative methods for solving risk parity portfolio [PDF]
Seonmul yeongu, 2022 Risk parity, also known as equal risk contribution, has recently gained increasing attention as a portfolio allocation method. However, solving portfolio weights must resort to numerical methods as the analytic solution is not available.

Deriving Fuzzy Weights from the Consistent Fuzzy Analytic Hierarchy Process
Mathematics, 2022 The analytic hierarchy process (AHP) is one of the most popular multi-criteria decision-making (MCDM) methods, and so is its extension fuzzy analytic hierarchy process (FAHP).
