Explicit formulas for matrices associated to ladder, circular ladder, and Mobius ladder graphs

Ali Azimi, Mohammad Farrokhi Derakhshandeh Ghouchan

We give explicit formulas for resistance distance matrices and Moore-Penrose inverses of incidence and Laplacian matrices of ladder, circular ladder, and Möbius ladder graphs. As a…

Gröbner basis and Krull dimension of Lovász-Saks-Sherijver ideal associated to a tree

Mohammad Farrokhi Derakhshandeh Ghouchan, Ali Akbar Yazdan Pour

Let $K$ be a field and $n$ be a positive integer. Let $Γ = ([n], E)$ be a simple graph, where $[n] = {1, \dots, n}$ . If $S = K [x_{1}, \dots, x_{n}, y_{1}, \dots, y_{n}]$ is…

Moore-Penrose inverse of incidence matrices

Ali Azimi, R. B. Bapat, Mohammad Farrokhi Derakhshandeh Ghouchan

We present explicit formulas for Moore-Penrose inverses of some families of set inclusion matrices arising from sets, vector spaces, and designs.
