MATHEMATICAL MODEL_Documented by Marsigit



MATHEMATICAL MODEL

A mathematical model for an axiomatic system is a well-defined set, which assigns meaning for the undefined terms presented in the system, in a manner that is correct with the relations defined in the system. The existence of a concrete model* proves the consistency of a system. 

Models can also be used to show the independence of an axiom in the system. By constructing a valid model for a subsystem without a specific axiom, we show that the omitted axiom is independent if its correctness does not necessarily follow from the subsystem. 

Two models are said to be isomorphic if one-to-one correspondence can be found between their elements, in a manner that preserves their relationship. An axiomatic system for which every model is isomorphic to another is called categorial, and the property of categoriallity ensures the completeness of a system. 

* A model is called concrete if the meanings assigned are objects and relations from the real world, as opposed to an abstract model which is based on other axiomatic systems.
The first axiomatic system was Euclidean geometry.

  1. Model matematika adalah suatu cara sederhana untuk mmenerjemahkan suatu masalah ke dalam bahasa matematika dengan menggunakan persamaan, pertidaksamaan, atau fungsi. Suatu model matematika sebagai pendekatan terhadap suatu fenomena (alami atau buatan) hanya mencakup sebanyak hingga pengamatan atau hanya mencakup daerah yang terbatas dari fenomena tersebut (yg tak terbatas) atau hanya bersifat diskrit, walaupun model tersebut masih dianggap sebagai bentuk yang sangat ideal dan yg sangat mendekati fenomena fisik aslinya
