Recent research interests and achievements.

 

As of 2020.03.24, Ngai-Ching Wong, has published totally 182 research papers in mathematics.  Among them, 162 was published in math research journals indexed in the list of WOS from ISI SCIE. There are 1813 citation records to his papers indexed by WOS, with an h-index 20. Wong has made important contributions to the Banach-Stone problem for function spaces and operator algebras.  His results are recorded in the famous collections of Fleming and Jamison, “Isometries on Banach spaces: function spaces, I & II (Chapman & Hall/CRC), and also in Chapters 9 and 10 of the new version of the classic of Narici and Beckenstein, “Topological Vector Spaces”, 2nd ed. (2012).

 

Below list some major contributions of Wong in recent years.

A.     Together with Chi-Wai Leung, Anthony To-Ming Lau and Chi-Keung Ng, Wong has studied the noncommutative  spaces.  In particular, the geometry of the positive contractive part and the positive sphere of the unit ball of an  space are showed to determine completely the Jordan structure of the underlying -algebra .  Their results apply to the study of the Fourier algebra  of a locally compact group or quantum group , and verify that the metric semigroup of the positive norm one functions in  determines  upto opposition.  Their contribution appears in a series of recent papers, including

1.        Chi-Wai Leung, Chi-Keung Ng and Ngai-Ching Wong*, “Bounded positive parts of noncommutative -spaces determine Jordan structures”, Linear Algebra and Applications, 519 (2017) pp. 102-110.

2.        Anthony To-Ming Lau, Chi-Keung Ng and Ngai-Ching Wong, “Metric semigroups that determine locally compact groups”, Quarterly J. Math. 69 (2018), 501–508.

3.        Chi-Wai Leung, Chi-Keung Ng and Ngai-Ching Wong, Metric preserving bijection between thin positive bells of non-commutative  -spaces, J. Operator Theory 80, Issue 2 (2018),  429-452.

4.        Anthony To-Ming Lau, Chi-Keung Ng and Ngai-Ching Wong, “Metric semi-groups of normal states determine F-algebras”, Quarterly J. Math 70 (2019), Issue 2, 429-450.

 

B.     Together with Chi-Keung Ng, Wong have finished two new and complete classification schemes of C*-algebras, in parallel with the seminal works of F. J. Murray and J. Von Neumann for W*-algebras.  Instead of using projections in the algebras, they used positive elements (following Cuntz and Pedersen) and open projections (following Peligrad and Zsido) for the classification tools. Their results appeared in

5.        “A Murray-von Neumann type classification of C*-algebras”, in “Operator semigroups meet complex analysis, harmonic analysis and mathematical physics”, Operator Theory: Advances and Applications, vol. 250, 369–395, Springer International Publ., 2015.

6.         “On the decomposition into discrete, type II and type III C*-algebras”, Math Proc. Camb. Phil. Soc., 165, Issue 3 (2018) , 475-509. 

7.         “Comparisons of equivalence relations on open projections”, J. Operator Theory 74, Issue 1, (2015), 101-123.

 

C.     Ngai-Ching Wong has obtained a rather deep and complete description of linear maps between operator algebras, which preserve norms, disjointness or orthogonality.  Together with Chung-Wen Tsai and Chi-Wai Leung, Wong provided a complete description of disjointness/orthogonality preserving linear maps between W*-algebras in

8.         “Linear disjointness preservers of W*-algebras”, Math. Z., 270 (2012), no. 3-4, 699–708.

These maps are exactly the algebra isomorphisms followed by a multiplier, i.e., . 

       Together with Anthony T.-M. Lau, Wong obtained a similar result for those disjointness/orthogonality preserving linear maps between preduals of W*-algebras, .  More precisely, such a map is a Jordan homomorphism  following a multiplication .  Consequently, they applied the result to Fourier algebras , which are preduals of the reduced group W*-algebra  They showed that every disjointness/ orthogonality preserving linear map  between the Fourier or the Fourier-Stieltjes of two locally compact groups carries the form ,  where  is a topological group isomorphism and  is a multiplier.  See, for details,

9.         “Orthogonality and disjointness preserving linear maps between Fourier and Fourier-Stieltjes algebras of locally compact groups”, J. Funct. Anal., 265(4) (2013), 562–593.

 

D.     In answering one of the four open problems raised by Micheal Frank about Hilbert C*-modules, Chi-Wai Leung, Chi-Keung Ng and Ngai-Ching Wong published a series of papers:

10.     “Linear orthogonality preservers of Hilbert bundles”, J. Australian Math. Soc., 89 (2010), no. 2, 245–254.

11.     “Linear orthogonality preservers of Hilbert C*-modules over C*-algebras with real rank zero”, Proc. Amer. Math. Soc., 140 (2012), no. 9, 3151–3160.

12.     “Linear orthogonality preservers of Hilbert C*-modules”, J. Operator Theory, 71:2(2014), 571–584.

They showed that every orthogonality preserving module map  between Hilbert A-modules preserving the A-valued inner products

is a unitary operator following a multiplier.  More precisely,

Where  is a central multiplier of the C*-algebra.

On the other hand, Ming-Hsiu Hsu and Ngai-Ching Wong also published a complete characterization of isometries between real C*-algebras in

13.    “Isometries of real Hilbert C*-modules”, J. Math. Anal. Appl., 438(2), 2016, 807–827

 

E.     Together with Jen-Chi Yao, B. T. Kien and D. R. Sahu, Ngai-Ching Wong have achieved quite a few good results in fixed point theory and algorithms, with applications to control and optimization theory.  Samples of their results can be found in

14.    “Necessary conditions for multiobjective optimal control problems with free end-time”, SIAM J. Control and Optimization, 47 (2008),  no. 5, 2251--2274.

15.     “A unified hybrid iterative method for solving variational inequalities involving generalized contractive mappings”, SIAM J. Control and Optimization, Vol. 50, No. 4 (2012), 2335–2354.
