On Measure Chaotic Dynamical Systems [PDF]
Sahand Communications in Mathematical Analysis, 2020 In this paper, we introduce chaotic measure for discrete and continuous dynamical systems and study some properties of measure chaotic systems. Also relationship between chaotic measure, ergodic and expansive measures is investigated. Finally, we prove a

Asymptotically CAT(0) groups [PDF]
, 2008 We develop a general theory for asymptotically CAT(0) groups; these are groups acting geometrically on a geodesic space, all of whose asymptotic cones are CAT(0)

A Formal Apology for Metaphysics [PDF]
, 2018 There is an old meta-philosophical worry: very roughly, metaphysical theories have no observational consequences and so the study of metaphysics has no value.

Two-Phase Turbulent Fluid Flow in a Geothermal Pipe with Chemical Reaction
Journal of Applied Mathematics, 2022 In this study, two-phase non-Newtonian turbulent fluid flow in an inclined geothermal pipe with chemical reaction was considered. The governing nonlinear partial differential equations derived were solved numerically using Finite Difference Method ...

Mathematical Models of Abstract Systems: Knowing abstract geometric forms [PDF]
, 2013 Scientists use models to know the world. It i susually assumed that mathematicians doing pure mathematics do not. Mathematicians doing pure mathematics prove theorems about mathematical entities like sets, numbers, geometric figures, spaces, etc., they ...

On the Explicit Formula for Eigenvalues, Determinant, and Inverse of Circulant Matrices
JTAM (Jurnal Teori dan Aplikasi Matematika), 2022 Determining eigenvalues, determinants, and inverse for a general matrix is computationally hard work, especially when the size of the matrix is large enough.

Stability of the gapless pure point spectrum of self-adjoint operators [PDF]
Journal of Mathematical Physics 65, 032102 (2024), 2022 We consider a self-adjoint operator $T$ on a separable Hilbert space, with pure-point and simple spectrum with accumulations at finite points. Explicit conditions are stated on the eigenvalues of $T$ and on the bounded perturbation $V$ ensuring the global stability of the spectral nature of $T+V$.
