comment Physical meaning of some identity in a weighted undirected graph
Sorry I have edited. Summing over all edges $(u,z)$ such that one end point is in $C$.

comment Solution to system of differential equation
@ Did This is not from a text book. My instructor is given some material to read ( on statistical physics). where they have not explained these things directly. Thanks for help.

comment Solution to system of differential equation
Sorry, This is the problem. $y'(t)= \frac{3}{8} x [-2\lambda y+x]$, $x'(t)= \frac{3}{8} x [-2(\lambda-1) y-(\lambda+3)x]+\frac{x}{2}$

comment Solution to system of differential equation
@ Did Thanks for help. I have small question, In one of the other exercise (similar to this) I have $X'(t)=\tfrac38x(t)\cdot A\cdot X(t) + W(t)$. where $W(t)=\begin{pmatrix}x(t)\\ y(t)\end{pmatrix}$. In this case how do we find asymptotic solution.

@Dr.SonnhardGraubner at least asymptotic limit.

comment Eigen vectors of symmetric matrix
Oh. But is there any procedure to choose orthogonal one. If possible can you provide some references to this type problems.
