Associated Homogeneous System definition

In summary, the conversation is about a system of linear equations and its associated homogeneous system. The system can be written in mathematical notation, where the left side is a linear combination of variables and the right side is a number. The associated homogeneous system is the same as the original system, but with all the numbers on the right side set to 0. The conversation ends with the person expressing gratitude for the help.

Hi, thank you for viewing this thread. I have been googling for its definition for quite a while, but have not found any yet. Just wondering if there is a definition of it, in mathematical notations and in words?

Any system of linear equations can be written in the form
[tex]a_{11}x_1+ a_{12}x_2+ \cdot\cdot\cdot+ a_{1n}x_n= b_1[/tex]
[tex]a_{21}x_1+ a_{22}x_2+ \cdot\cdot\cdot+ a_{2n}x_n}= b_2[/tex]
etc.

That is, the left side of each equation is a linear combination of the variables, and the right side is a number. The "associated homogenous system" is exactly the same with the numbers on the right side all set to 0.

The "associated homogenous system" for the above system is:
[tex]a_{11}x_1+ a_{12}x_2+ \cdot\cdot\cdot+ a_{1n}x_n= 0[/tex]
[tex]a_{21}x_1+ a_{22}x_2+ \cdot\cdot\cdot+ a_{2n}x_n= 0[/tex]
etc.

Alright, I got it. Thanks for your help!
 

1. What is an Associated Homogeneous System?

An Associated Homogeneous System is a set of equations where each equation has the same number of variables and the same degree of each variable. This means that the system can be solved by eliminating the variables one by one until only one equation with one variable remains.

2. How is an Associated Homogeneous System different from a Non-Homogeneous System?

An Associated Homogeneous System has all equations with a constant term of zero, while a Non-Homogeneous System has at least one equation with a non-zero constant term. This means that an Associated Homogeneous System has only the trivial solution of all variables equaling zero, while a Non-Homogeneous System may have non-trivial solutions.

3. What is the importance of Associated Homogeneous Systems in mathematics?

Associated Homogeneous Systems are important in mathematics because they can be used to solve systems of equations with many variables. They also have applications in linear algebra, differential equations, and other areas of mathematics.

4. How are Associated Homogeneous Systems solved?

To solve an Associated Homogeneous System, the variables are eliminated one by one until only one equation with one variable remains. This can be done using various methods such as substitution, elimination, or Gaussian elimination.

5. Can an Associated Homogeneous System have infinite solutions?

Yes, an Associated Homogeneous System can have infinite solutions if the system is underdetermined, meaning there are more variables than equations. In this case, there will be free variables that can take on any value, resulting in an infinite number of solutions.
