Magnetic cochains Laplacians and their essential self-adjointness

Abstract

In this paper, we introduce the notion of oriented triangular faces [Formula: see text], the notion of edges potential [Formula: see text] and the notion of triangular faces potential [Formula: see text] in a connected oriented locally finite graph [Formula: see text] in order to construct a new framework that’s we call the magnetic weighted 2-simplicial complex [Formula: see text]. On this new magnetic weighted framework, we introduce the magnetic 0-cochains set, the magnetic 1-cochains set, the magnetic 2-cochains set and the magnetic cochains set. After that, we construct the magnetic 0-cochains Laplacian, the magnetic 1-cochains Laplacian, the magnetic 2-cochains Laplacian and the magnetic cochains Laplacian. Finally, we ensure essential self-adjointness for our new magnetic cochains Laplacians using the Stieltjes vectors.
