Green's function product problem

[kunyuan]

Assume G1(tau) is bosonic, and G2(tau) is fermionic. Right now, the code allows G1*G2. The statistics of the resulting product is not well defined in the code.

Hi Kun,

Thanks for your feed back. In our implementation, the arithmetic operations of two MeshArrays are designed for Green's functions on exactly the same meshes. For the situation you mentioned, the user need to align the meshs of G1 and G2 with the transformation tools provided in our package. In the future, we plan to add a tensor product operation for more generic situations.

Best,

Tao Wang
