If a linear transformation acts on a vector and the result is only a change in the vector's magnitude, not direction, that vector is called an eigenvector of that particular linear transformation, and the magnitude that the vector is changed by is called an eigenvalue of that eigenvector.
Formulaically, this statement is expressed as Av=kv, where A is the linear transformation, vis the eigenvector, and k is the eigenvalue. Keep in mind that A is usually a matrix and k is a scalar multiple that must exist in the field of which is over the vector space in question.
No. Say your matrix is called A, then a number e is an eigenvalue of A exactly when A-eI is singular, where I is the identity matrix of the same dimensions as A. A-eI is singular exactly when (A-eI)T is singular, but (A-eI)T=AT-(eI)T =AT-eI. Therefore we can conclude that e is an eigenvalue of A exactly when it is an eigenvalue of AT.

The term "eigenvalue" refers to a noun which means each set of values of parameter for which differential equation has a nonzero solution. It can also refers to any number such that given matrix subtracted by the same number and multiply to the identity matrix has a zero determinant.
Yes, do write. That's what you always have to do when you have got a homework-program.
This is the definition of eigenvectors and eigenvalues according to Wikipedia:Specifically, a non-zero column vector v is a (right) eigenvector of a matrix A if (and only if) there exists a number λ such that Av = λv. The number λ is called the eigenvalue corresponding to that vector. The set of all eigenvectors of a matrix, each paired with its corresponding eigenvalue, is called the eigensystemof that matrix
To find the largest eigenvalue of a matrix, you can use methods like the power iteration method or the QR algorithm. These methods involve repeatedly multiplying the matrix by a vector and normalizing the result until it converges to the largest eigenvalue.
No.
The maximum eigenvalue is important in determining the stability of a system because it indicates how quickly the system will reach equilibrium. If the maximum eigenvalue is less than 1, the system is stable and will converge to a steady state. If the maximum eigenvalue is greater than 1, the system is unstable and may exhibit oscillations or diverge over time.
When an eigenvalue of a matrix is equal to 0, it signifies that the matrix is singular, meaning it does not have a full set of linearly independent eigenvectors.

Yes, it is.
No. Say your matrix is called A, then a number e is an eigenvalue of A exactly when A-eI is singular, where I is the identity matrix of the same dimensions as A. A-eI is singular exactly when (A-eI)T is singular, but (A-eI)T=AT-(eI)T =AT-eI. Therefore we can conclude that e is an eigenvalue of A exactly when it is an eigenvalue of AT.

Yes it is. In fact, every singular operator (read singular matrix) has 0 as an eigenvalue (the converse is also true). To see this, just note that, by definition, for any singular operator A, there exists a nonzero vector x such that Ax = 0. Since 0 = 0x we have Ax = 0x, i.e. 0 is an eigenvalue of A.
In quantum mechanics, the energy eigenvalue represents the specific energy level that a quantum system can have. It is significant because it helps determine the possible states and behaviors of the system, providing crucial information about its properties and dynamics.
The maximal eigenvalue of a matrix is important in matrix analysis because it represents the largest scalar by which an eigenvector is scaled when multiplied by the matrix. This value can provide insights into the stability, convergence, and behavior of the matrix in various mathematical and scientific applications. Additionally, the maximal eigenvalue can impact the overall properties of the matrix, such as its spectral radius, condition number, and stability in numerical computations.
