Comment: Please see the BLP you reference, i.e. Brian Alspach and Carsten Thomassen for format. As said earlier, you can't use web links, everything has to be a proper reference. Please also ensure that the sources are appropriate. For instance, [1] is presumably a paper from his thesis, but it does not prove he in fact completed one! For that a reference to his actual thesis is appropriate. I. BLP it is amost guilty until proven innocent. Ldm1954 (talk) 20:14, 7 July 2024 (UTC)

Comment: I think he passes WP:PROF#C5 as a named distinguished professor at a major research university. But the external links from article text need to be removed and replaced by proper sources. Independence of the sources is not required for PROF notability but reliability of sources for all content is still a requirement. —David Eppstein (talk) 05:42, 17 June 2024 (UTC)

Comment: Fails WP:ANYBIO requires significant coverage in multiple independent secondary sources. WVU is a primary source. Dan arndt (talk) 05:19, 19 May 2024 (UTC)

C. Q. Zhang (full name: Cun-Quan Zhang, born 1952) is a mathematician working mainly in graph theory, currently a professor emeritus at the West Virginia University.

Education

C. Q. Zhang was admitted by Simon Fraser University in 1982, earned his Ph.D. (mathematics) in 1987 under the supervision of Prof. Brian Alspach [1].

Biography

C. Q. Zhang is Eberly Distinguished Professor in Mathematics at West Virginia University,

C. Q. Zhang served as a Managing Editor of The Australasian Journal of Combinatorics.

Research

C. Q. Zhang is known for his work in graph theory, and particularly for some works in the subjects of nowhere-zero flow problems, cycle double cover problems, Hamilton cycle problems: see Zhang's publications on AMS' MATHSCINET and on Google Scholar.

Some major results in Zhang's research include the following:

Cycle double cover conjecture. He (collaborated with Brian Alspach) proved that every graph without the Petersen minor has a cycle double cover^[1]^[2]^[3].
Nowhere-zero flow. He (collaborated with László M Lovász, Carsten Thomassen, Yezhou Wu) proved that every 6-connected graph admits a nowhere-zero-3-flow, which is the best partial result to Tutte’s 3-flow conjecture^[4]. And other major results^[5]^[6].
Hamilton cycle problems for graphs, especially his method of vertex inserting ^[7].

Awards and honors

Benedum Distinguished Scholar Award from West Virginia University

Eberly Distinguished Professor of Mathematics at West Virginia University.
