Nonlinear biseparating maps

Xianzhe Feng, Denny H. Leung

An additive map $T$ acting between spaces of vector-valued functions is said to be biseparating if $T$ is a bijection so that $f$ and $g$ are disjoint if and only if $T f$ and $T g$ …

The least signless Laplacian eigenvalue of the complements of bicyclic graphs

Xiaoyun Feng, Guoping Wang

Suppose that $G$ is a connected simple graph with the vertex set $V (G) = {v_{1}, v_{2}, \dots, v_{n}}$ . Then the adjacency matrix of $G$ is $A (G) = (a_{ij})_{n \times n}$ , where $a_{ij} = 1$ i…
