What is the solution of Dirac delta function of density of sate equation below:
DOS(E)=2/N ∑ ∫(1/dE_{j}(k)/dk).δ[Ej(k)E]dE

are you sure this expression makes sense? Maybe I miss something?

[tex]\frac{1}{2}Ax= b[/tex] and state your problem clearer.

Density of state
Thank you, I'm attaching the equation in word denouement.

This is basically the density of state at energy E from N_hex bands. The delta function filters out the energy spectrum at E_j(k_t)=E. 1/dE/dk gives density of state at E from the given band

Do you mean the final equation become like this DOS(E)=E. 1/dEj/dk
please do you have a reference of this solution ?

should be DOS(E)= sum_j (1/dEj/dk). Take a look at Ashcroft and Mermin's solid state physics
