Homework Statement I have a matrix A [1 -1 -1 -1; -1 1 -1 -1; -1 -1 1 -1; -1 -1 -1 1], its characteristic polynomial p(t) = (t + 2)(t-2)3, and given value of lambda = 2. I need to find basis for eigenspace, and determine algebraic and geometric multiplicities of labmda.Homework Equations The...

Homework Statement Prove that if two matrices are similar then they have the same eigenvalues with the same algebraic and geometric multiplicity. Homework Equations Matrices A,B are similar if A = C\breve{}BC for some invertible C (and C inverse is denoted C\breve{} because I tried for a...

On the multiplicity of the eigenvalue Dear friends, Might you tell me any hint on the multiplicity of the max eigenvalue, i.e., one, of the following matrix. 1 0 0 0 0 p21 0 p23 0 0 0 p32 0 p34 0...

Homework Statement Given matrix A: a 1 1 ... 1 1 a 1 ... 1 1 1 a ... 1 .. . .. ... 1 1 1 1 ... a Show there is an eigenvalue of A whose geometric multiplicity is n-1. Express its value in terms of a. Homework Equations general eigenvalue/vector equations The Attempt at a Solution My...

I am somewhat confused about this property of an eigenvalue when A is a symmetric matrix, I will state it exactly as it was presented to me. "Properties of the eigenvalue when A is symmetric. If an eigenvalue \lambda has multiplicity k, there will be k (repeated k times), orthogonal...

Homework Statement Let f has a zero of multiplicity k at 0. Find the residue of f'/f at 0 The Attempt at a Solution I'm kind of get stuck on this one. I got only this far: Since f has a zero of multiplicity k at 0, then f(z) = (z^k)g(z) :( Thanks a lot for helping!

Homework Statement Use the equation ln(q+N) to derived an equation similar to the equation, omega(N,q)=e^(N*ln(q/N))*e^(N)=(eq/N)^N only when q >> N, for a multiplicity of an einstein solid in the "low temperature" limit , q<<N Homework Equations ln(q+N) ln...

Homework Statement (a) The formula for the multiplicity of an Einstein solid in the “high-temperature” limit, q >> N, was derived in one of the lectures. Use the same methods to show that the multiplicity of an Einstein solid in the “low-temperature” limit, q << N, is Ω(N,q)=(eN/q)^q...

Homework Statement Consider a monatomic ideal gas that lives in a two-dimensional universe (“flatland”), occupying an area A instead of a volume V. (a) By following the logic of the derivation for the three-dimensional case, show that the multiplicity of this gas can be written...

Consider an isolated system of two ideal, identical gases in thermal equilibrium. Gas A is occupying a volume A, separated by a wall from volume B, where gas B resides. They are in thermal contact. The volumes are the same, so are the pressures and temperatures, and it follows that the number of...

Homework Statement Suppose A and B are similar matrices, and that (mu) is an eigenvalue of A. We know that (mu) is also an eigenvalue of B, with the same algebraic multiplicity(proved in class) Suppose that g is the geometric multiplicity of (mu), as an eigenvalue of B. Show that (mu) has...

Does the multiplicity of zero of characteristic polynomial restrict from above the possible dimension of the corresponding eigenspace? For example if we have a 3x3 matrix A, and a characteristic polynomial \textrm{det}(\lambda - A)=\lambda^2(\lambda - 1) I can see that the eigenspace...

if A* is the adjoint of A in Complx, Then is A* x A* = (A^2)* or something else??

In complex analysis, what is understood by the multiplicity of a pole? thank you

Can someone please explain multiplicity to me? I've been able to solve the problems involving it, but I'm not quite sure what it means in terms of the eigenvalue. Thanks.

1. What will be the multiplicity due to spin-spin splitting of the highlighted protons in the molecule: (C6H5)-CH2-CH2-CH2-OH? Homework Equations None The Attempt at a Solution I know that the ones surrounding the highlighted CH2 group are not equivalent. If they were, the...

I'm studying for a linear algebra final, and I'm looking over an old final our prof gave us and I've come across something I don't remember ever hearing anything about... Here's the problem: Write down a matrix A for the following condition: A is a 3x3 matrix with lambda=4 with algebraic...

In order to get a "feeling" of the sharpness of the multiplicity function, for a system of 2 solids (A & B) with N quantum oscillators in each, in the high-temeperature limit (that is the total number of energy units q is much larger than N), it is approximated as a Gaussian as [Shroeder, eq...

Hi all, I have a homework problem that I would like someone to check: this relates to the eigenvectors: in the problem we are given characteristic polynomial, where I put x instead of lambda: p(x) = x^2*(x+5)^3*(x -7)^5 Also given A is a square matrix, and then these questions (my answers)...

I'm reading a chapter on recurrence relations and they have a problem with the phrase: ...if r is a root with multiplicity 2. What does it mean for a root to have multiplicity? This is the first time I've heard of this and the book assumes I would know what they mean already.

Consider an ideal monatomic gas that lives in a two-dimensional universe ("flatland"), occupying an area A instead of a volume V. Find a formula for the multiplicity of this gas. I arrived at this formula. Is it correct?: 1/N!(A^N/h3N)(pi^3N/2/3N/2)!(sqrt(2mU))^3N
