Fractional Coloring Planar Graphs under Steinberg-type Conditions

Acta Mathematica Sinica, English Series, 2022
A Steinberg-type conjecture on circular coloring recently proposed that for any prime \(p\geq 5\), every planar graph of girth \(p\) without cycles of length \(q\), with \(p+1\leq q\leq p(p-2)\), is \(C_p\)-colorable (that is to say, it admits a homomorphism to the cycle \(C_p\)). This conjecture implies a special case of \textit{F.

Densities, Matchings, and Fractional Edge-Colorings

SIAM Journal on Optimization, 2019
Summary: Given a multigraph \(G=(V,E)\) with a positive rational weight \(w(e)\) on each edge \(e\), the weighted density problem (WDP) is to find a subset \(U\) of \(V\), with \(| U|\geq 3\) and odd, that maximizes \(2w(U)/(| U|-1)\), where \(w(U)\) is the total weight of all edges with both ends in \(U\), and the weighted fractional edge-coloring ...

Real color fractional Fourier transform holograms

Optics Communications, 2006
Real color fractional Fourier transform holography is proposed based on fractional Fourier transform holography. The method of fabrication, the principle of reconstruction and the design of system parameters are discussed in detail. The experiments prove real color fractional Fourier transform holograms possess the better function of anti-counterfeit ...
