ANALYSIS OF MATHEMATICS LITERACY BASED ON MATHEMATICAL ABILITY

Scholaria : Jurnal Pendidikan dan Kebudayaan, 2017
This research was conducted to determine the literacy skills students of class X on their math skill. This study used a qualitative approach, the approach that drives meaningful results. To determine the ability of mathematical literacy class X, there were study subjects of 3 people who were selected based on their level of math skills.

Global Perturbation of Nonlinear Eigenvalues

Advanced Nonlinear Studies, 2021
This paper generalizes the classical theory of perturbation of eigenvalues up to cover the most general setting where the operator surface 𝔏:[a,b]×[c,d]→Φ0⁢(U,V){\mathfrak{L}:[a,b]\times[c,d]\to\Phi_{0}(U,V)}, (λ,μ)↦𝔏⁢(λ,μ){(\lambda,\mu)\mapsto\mathfrak ...

A Mathematical Framework for Agent Based Models of Complex Biological Networks [PDF]

, 2010
Agent-based modeling and simulation is a useful method to study biological phenomena in a wide range of fields, from molecular biology to ecology. Since there is currently no agreed-upon standard way to specify such models it is not always easy to use ...

GROUP CLASSIFICATION FOR A GENERAL NONLINEAR MODEL OF OPTIONS PRICING

Ural Mathematical Journal, 2016
We consider a family of equations with two free functional parameters containing the classical Black–Scholes model, Schönbucher–Wilmott model, Sircar–Papanicolaou equation for option pricing as partial cases.

Marriages of Mathematics and Physics: A Challenge for Biology [PDF]

, 2017
The human attempts to access, measure and organize physical phenomena have led to a manifold construction of mathematical and physical spaces. We will survey the evolution of geometries from Euclid to the Algebraic Geometry of the 20th century.

Global solution to the compressible non-isothermal nematic liquid crystal equations with constant heat conductivity and vacuum

Advances in Difference Equations, 2021
This paper considers the initial-boundary value problem of the one-dimensional full compressible nematic liquid crystal flow problem. The initial density is allowed to touch vacuum, and the viscous and heat conductivity coefficients are kept to be ...
