Spread the loveA quadratic function is a polynomial equation of degree two which typically takes the form of y = ax^2 + bx + c, where a, b, and c are constants. The vertex of a quadratic function is ...

This method, called the vertex-frequency analysis, relies on Laplacian matrices to establish connections between vertex changes and spectral content [2]- [5]. Specifically, this lecture note aims to ...

Graph coloring is a fundamental problem in combinatorics with many applications in practice. In this problem, the vertices in a given graph must be colored by using the least number of colors in such ...
