Spectral radius and matchings in graphs

Linear Algebra and its Applications, 2021
A perfect matching in a graph G is a set of disjoint edges covering all vertices of G. Let ρ ( G ) be the spectral radius of a graph G, and let θ ( n ) be the largest root of x 3 − ( n − 4 ) x 2 − ( n − 1 ) x + 2 ( n − 4 ) = 0 .

New upper bounds for the numerical radius of Hilbert space operators

, 2021
In this paper we present new upper bounds for the numerical radius of bounded linear operators defined on a complex Hilbert space. Further we obtain estimations for upper bounds for the numerical radius of the sum of the product of bounded linear ...

Optimizing matching time interval and matching radius in on-demand ride-sourcing markets

Transportation Research Part B: Methodological, 2020
With the availability of the location information of drivers and passengers, ride-sourcing platforms can now provide increasingly efficient online matching compared with physical searching and meeting performed in the traditional taxi market.
