Hi i want to ask if there is any way ti compute symbolically the Green's function of a matrix A?

09 September 2016 1 2K Report

where Green's function G=G(t) is given by:

dG(t)/dt=AG+δI where δ is dirac delta function.

The Green's function G(t) can be computed symbolically in a computer algebra system, such as Mathematica. Namely, dG(t)/dt=AG+δI is a system of differential equations. It is possible to apply the Mathematica function Dsolve to each of these equations and generate the matrix G(t).

Do you need the CMV enhancer before the CMV promotor for a proper function of CMV on the gene that follows?

I'm a student and I have to produce a cell line with a knockin for the NRF2 gene with GFP. I have to put a promotor in front of the GFP because the gene will be too far away from the promotor of...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
