Reflected BSDE with stochastic Lipschitz coefficient
Wen Lu
Mathematics , 2009,
Abstract: In this paper, we deal with a class of one-dimensional reflected backward stochastic differential equations with stochastic Lipschitz coefficient. We derive the existence and uniqueness of the solutions for those equations via Snell envelope and the fixed point theorem.
$L^p$-solutions of Reflected Backward Doubly Stochastic Differential Equations
Wen Lu
Mathematics , 2009,
Abstract: In this paper, we deal with a class of one-dimensional reflected backward doubly stochastic differential equations with one continuous lower barrier. We derive the existence and uniqueness of solutions for these equations with Lipschitz coefficients.
The second coefficient of the asymptotic expansion of the Bergman kernel of the Hodge-Dolbeault operator
Wen Lu
Mathematics , 2012,
Abstract: We calculate the second coefficient of the asymptotic expansion of the Bergman kernel of the Hodge-Dolbeault operator associated to high powers of a Hermitian line bundle with non-degenerate curvature, using the method of formal power series developed by Ma and Marinescu.
A Thom-Smale-Witten theorem on manifolds with boundary
Wen Lu
Mathematics , 2012,
Abstract: Given a smooth compact manifold with boundary, we show that the subcomplex of the deformed de Rham complex consisting of eigenspaces of small eigenvalues of the Witten Laplacian is canonically isomorphic to the Thom-Smale complex constructed by Laudenbach. Our proof is based on Bismut-Lebeau's analytic localization techniques. As a by-product, we obtain Morse inequalities for manifolds with boundary.
Equivariant Morse inequalities and applications
Wen Lu
Mathematics , 2012,
Abstract: In this paper, we prove equivariant Morse inequalities via Bismut-Lebeau's analytic localization techniques. As an application, we obtain Morse inequalities on compact manifold with nonempty boundary by applying equivariant Morse inequalities to the doubling manifold.
Backward stochastic Volterra integral equations associated with a Levy process and applications
Wen Lu
Mathematics , 2011,
Abstract: In this paper, we study a class of backward stochastic Volterra integral equations driven by Teugels martingales associated with an independent L\'{e}vy process and an independent Brownian motion (BSVIELs). We prove the existence and uniqueness as well as stability of the adapted M-solutions for those equations. Moreover, a duality principle and then a comparison theorem are established. As an application, we derive a class of dynamic risk measures by means of M-solutions of certain BSVIELs.
An “Embedded” Mode of International Talent Training Boosts the Two-Way Opening of Higher Education  [PDF]
Weibo Zheng, Yilei Wen, Lu Zheng
Open Journal of Social Sciences (JSS) , 2019, DOI: 10.4236/jss.2019.73010
Abstract:
The Belt and Road Initiative (BRI) introduces new demands for international talents, and the strategy for the coordinated development of Beijing, Tianjin and Hebei Province which gives new opportunities to train such talents in Hebei Province. In this context, relevant adjustments shall be made into the training of international talents in order to better meet the needs of the times. This paper outline the “embedded” international talent cultivation, a practice carried out in Hebei in the two-way opening of higher education, which is aim to cultivate international management talents who understand international laws, master economic management expertise in the context of globalization, have innovative ability, cross-cultural competence, practical ability and high foreign language ability, are familiar with international business activities and rules, and able to work in enterprises and institutions. It is a practice to pose quality education resources from abroad while building on cultural confidence. This article also offers a peek into the export of culture and its contribution to the two-way opening of higher education.
Synthesis of Propargyl-Terminated Heterobifunctional Poly(ethylene glycol)
Changhai Lu,Wen Zhong
Polymers , 2010, DOI: 10.3390/polym2040407
Abstract: Novel propargyl-ended heterobifunctional poly(ethylene glycol) (PEG) derivatives with hydroxyl, carboxyl, mercapto or hydrazide end groups were synthesized with simplicity yet high efficiency. PEG ( M w = 3500 Da) with an α-hydroxyl group and an ω-carboxyl was used as the starting polymer. The carboxyl group of the bifunctional PEG was modified into a propargyl, then carboxyl, mercapto or hydrazide groups were introduced to the other end of the bifunctional PEG by modifying the bifunctional PEG’s hydroxyl group with succinic anhydride, cysteamide or tert-butyl carbazate, respectively. This method can be useful to the development of PEG-based bioconjugates for a variety of biomedical applications.
Discussion on IGMP Snooping and Its Sequence in Industrial Applicaiton
Sheng LU,Chuan WEN
International Journal of Wireless and Microwave Technologies , 2011, DOI: 10.5815/ijwmt.2011.02.07
Abstract: This paper has an introduction on a new intelligent controller for industrial Ethernet with IGMP: ICIE (Intelligent Controller for Industrial Ethernet). It proposed a new mechanism to minimize the congestion which is based on the taking an adaptive decision during transferring multicast messages. It also focuses on the sequences analysis on IGMP snooping. It has a further discussion on the steps: receiving IGMP loin message, receiving IGMP leave message, receiving IGMP query message, sending IGMP join message, sending IGMP leave message and network topology change. According to the requirement of end device ring topology, we add a DSA tagged BPDU to indict the target of packet. It is through the external devices solicitation of join messages that allow the IGMP Snooping component to correctly decipher on which ports the downstream listeners are connected.
The (1+1)-dimensional Massive sine-Gordon Field Theory and the Gaussian Wave-functional Approach
Wen-Fa Lu
Physics , 1998, DOI: 10.1103/PhysRevD.59.105021
Abstract: The ground, one- and two-particle states of the (1+1)-dimensional massive sine-Gordon field theory are investigated within the framework of the Gaussian wave-functional approach. We demonstrate that for a certain region of the model-parameter space, the vacuum of the field system is asymmetrical. Furthermore, it is shown that two-particle bound state can exist upon the asymmetric vacuum for a part of the aforementioned region. Besides, for the bosonic equivalent to the massive Schwinger model, the masses of the one boson and two-boson bound states agree with the recent second-order results of a fermion-mass perturbation calculation when the fermion mass is small.
