-Estimates of the Bergman projection in the Lie ball of
Cyrille Nana
Journal of Function Spaces and Applications , 2011, DOI: 10.1155/2011/291620
Abstract: In this paper, we consider estimates with loss for the Bergman projections of bounded symmetric domains of ℂn in their Harish-Chandra realizations. This paper is twofold: on one side we develop transfer methods between these bounded domains and their Cayley transform; on the other side we give a new range of q such that the Bergman projection is bounded from L∞(ℬn) to Lq(ℬn) where ℬn is the Lie ball of ℂn.

Journal of Function Spaces , 2011, DOI: 10.1155/2011/291620
Abstract: In this paper, we consider estimates with loss for the Bergman projections of bounded symmetric domains of ? n in their Harish-Chandra realizations. This paper is twofold: on one side we develop transfer methods between these bounded domains and their Cayley transform; on the other side we give a new range of q such that the Bergman projection is bounded from L ∞ ( ? n ) to L q ( ? n ) where ? n is the Lie ball of ? n .
Carleson embeddings and two operators on Bergman spaces of tube domains over symmetric cones
Cyrille Nana,Benoit F. Sehba
Mathematics , 2014,
Abstract: We prove Carleson embeddings for Bergman spaces of tube domains over symmetric cones, we apply them to characterize symbols of bounded Ces\`aro-type operators from weighted Bergman spaces to weighted Besov spaces. We also obtain Schatten class criteria of Toeplitz operators and Ces\`aro-type operators on weighted Hilbert-Bergman spaces.
Toeplitz and Hankel operators from Bergman to analytic Besov spaces of tube domains over symmetric cones
Cyrille Nana,Benoit F. Sehba
Mathematics , 2015,
Abstract: We characterize bounded Toeplitz and Hankel operators from weighted Bergman spaces to weighted Besov spaces in tube domains over symmetric cones. We deduce weak factorization results for some Bergman spaces of this setting.

Reasons, Consequences and Solutions to Anti-Business Logic Behavior of State-Owned Enterprises Controllers  [PDF]
Nana Zhang
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.88119
Abstract: Focusing on the anti-business logic behavior of state-owned enterprises controllers, this paper finds that the behavior is characterized by lack of cost constraints, control of commodity prices to make it lower than market equilibrium price, stressing on scale while neglecting efficiency, etc., which causes consequences of overcapacity in some state-owned enterprises, zombie enterprises, the loss of state-owned assets, financial burdens for the state, and unequal market status for private enterprises. Finally, the paper puts forward effective solutions.
Probabilistic Fuzzy Regression Approach from the Point of View Risk  [PDF]
Nana Gao, Qiujun Lu
Journal of Data Analysis and Information Processing (JDAIP) , 2018, DOI: 10.4236/jdaip.2018.64010
Abstract: Fuzzy regression analysis is an important regression analysis method to predict uncertain information in the real world. In this paper, the input data are crisp with randomness; the output data are trapezoid fuzzy number, and three different risk preferences and chaos optimization algorithm are introduced to establish fuzzy regression model. On the basis of the principle of the minimum total spread between the observed and the estimated values, risk-neutral, risk-averse, and risk-seeking fuzzy regression model are developed to obtain the parameters of fuzzy linear regression model. Chaos optimization algorithm is used to determine the digital characteristic of random variables. The mean absolute percentage error and variance of errors are adopted to compare the modeling results. A stock rating case is used to evaluate the fuzzy regression models. The comparisons with five existing methods show that our proposed method has satisfactory performance.
Particle production and saturation at RHIC and LHC
Marquet, Cyrille
High Energy Physics - Phenomenology , 2008,
Abstract: The Color Glass Condensate picture of the nuclear wave function at small-x successfully predicted the suppressed production of high-pT particles at forward rapidities in deuteron-gold collisions at RHIC. This triggered more efforts which resulted in theoretical improvements and predictions for different observables which will provide further phenomenological tests. I review recent theoretical developments and discuss the resulting predictions.
Forward inclusive dijet production and azimuthal correlations in pA collisions
Marquet, Cyrille
High Energy Physics - Phenomenology , 2007, DOI: 10.1016/j.nuclphysa.2007.09.001
Abstract: We derive forward inclusive dijet production in the scattering of a dilute hadron off an arbitrary dense target, whose partons with small fraction of momentum x are described by a Color Glass Condensate. Both multiple scattering and non-linear QCD evolution at small-x are included. This is of relevance for measurements of two-particle correlations in the proton direction of proton-nucleus collisions at RHIC and LHC energies. The azimuthal angle distribution is peaked back to back and broadens as the momenta of the measured particles gets closer to the saturation scale.
Hard diffraction and the Color Glass Condensate
Marquet, Cyrille
High Energy Physics - Phenomenology , 2007,
Abstract: Following the Good-and-Walker picture, hard diffraction in the high-energy/small-x limit of QCD can be described in terms of eigenstates of the scattering matrix off a Color Glass Condensate. From the CGC non-linear evolution equations, it is then possible to derive the behavior of diffractive cross-sections at small $x.$ I discuss recent results, in particular the consequences of the inclusion of Pomeron loops in the evolution.
