In this paper we study a bilinear optimal control problem for a diffusive Lotka-Volterra competition model with chemo-repulsion in a bounded domain of ℝℕ, N = 2, 3. This model describes the competition of two species in which one of them avoid encounters with rivals through a chemo-repulsion mechanism. We prove the existence and uniqueness of weak-strong solutions, and then we analyze the existence of a global optimal solution for a related bilinear optimal control problem, where the control is acting on the chemical signal. Posteriorly, we derive first-order optimality conditions for local optimal solutions using the Lagrange multipliers theory. Finally, we propose a discrete approximation scheme of the optimality system based on the gradient method, which is validated with some computational experiments.

This paper studies a strongly convergent inertial forward-backward-forward algorithm for the variational inequality problem in Hilbert spaces. In our convergence analysis, we do not assume the on-line rule of the inertial parameters and the iterates, which have been assumed by several authors whenever a strongly convergent algorithm with an inertial extrapolation step is proposed for a variational inequality problem. Consequently, our proof arguments are different from what is obtainable in the relevant literature. Finally, we give numerical tests to confirm the theoretical analysis and show that our proposed algorithm is superior to related ones in the literature.

Let n ≥ 2 and let L be a second-order elliptic operator of divergence form with coefficients consisting of both an elliptic symmetric part and a BMO anti-symmetric part in ℝn. In this article, we consider the weighted Kato square root problem for L. More precisely, we prove that the square root L1/2 satisfies the weighted Lp estimates (||{L^{1/2}}(f)|{|_{L_omega ^p({mathbb{R}^n})}} le C||nabla f|{|_{L_omega ^p({mathbb{R}^n};{mathbb{R}^n})}}) for any p ∈ (1, ∞) and ω ∈ Ap(ℝn) (the class of Muckenhoupt weights), and that (||nabla f|{|_{L_omega ^p({mathbb{R}^n};{mathbb{R}^n})}} le C||{L^{1/2}}(f)|{|_{L_omega ^p({mathbb{R}^n})}}) for any p ∈ (1, 2 + ε) and ω ∈ Ap(ℝn) ∩ (R{H_{({{2 + varepsilon } over p})prime }}({mathbb{R}^n})) (the class of reverse Hölder weights), where ε ∈ (0, ∞) is a constant depending only on n and the operator L, and where (({{2 + varepsilon } over p})prime ) denotes the Hölder conjugate exponent of ({{2 + varepsilon } over p}). Moreover, for any given q ∈ (2, ∞), we give a sufficient condition to obtain that (||nabla f|{|_{L_omega ^p({mathbb{R}^n};{mathbb{R}^n})}} le C||{L^{1/2}}(f)|{|_{L_omega ^p({mathbb{R}^n})}}) for any p ∈ (1, q) and (omega in {A_p}({mathbb{R}^n}) cap R{H_{({q over p})prime }}({mathbb{R}^n})). As an application, we prove that when the coefficient matrix A that appears in L satisfies the small BMO condition, the Riesz transform ∇L−1/2 is bounded on Lpω(ℝn) for any given p ∈ (1, ∞) and ω ∈ Ap(ℝn). Furthermore, applications to the weighted L2-regularity problem with the Dirichlet or the Neumann boundary condition are also given.
设 n ≥ 2，设 L 为发散形式的二阶椭圆算子，其系数由 ℝn 中的椭圆对称部分和 BMO 反对称部分组成。更准确地说，我们证明平方根 L1/2 满足加权 Lp 估计值 (||{L^{1/2}}(f)|{{|{L_omega ^p({mathbb{R}^n})}}.|{L^{1/2}}(f)|{{L_omega ^p({/mathbb{R}^n})}}}；{对于任意 p∈ (1, ∞) 和 ω∈ Ap(ℝn)（Muckenhoupt 权重类），并且 (||nabla f|{|{_L_omega ^p({/mathbb{R}^n};{/mathbb{R}^n})}}})。对于任意 p∈ (1, 2 + ε) 且 ω∈ Ap(ℝn) ∩(R{H_{({{2 + varepsilon } over p})prime}}({/mathbb{R}^n})}（反向荷尔德权重类），|{{L^{1/2}}(f)|{|_{L_omega ^p({/mathbb{R}^n})}}(le C||{L^{1/2}}(f)|{|{{L_omega ^p({mathbb{R}^n})}})、其中 ε∈ (0, ∞) 是一个常数，只取决于 n 和算子 L，而 (({{2 + varepsilon } over p})prime ) 表示 ({{2 + varepsilon } over p}) 的霍尔德共轭指数。此外，对于任意给定的 q∈ (2, ∞)，我们给出了一个充分条件，即 (||nabla f|{|{L_omega ^p({mathbb{R}^n};{mathbb{R}^n})}})对于任意 p∈ (1, q) 并且 (omega in {A_p}({mathbb{R}^n}) cap R{H_{({q over p})prime }}({mathbb{R}^n})).作为应用，我们证明了当 L 中出现的系数矩阵 A 满足小 BMO 条件时，对于任意给定的 p∈ (1, ∞) 和 ω∈ Ap(ℝn) ，里兹变换 ∇L-1/2 在 Lpω(ℝn) 上是有界的。此外，还给出了迪里夏特或诺伊曼边界条件下加权 L2- 不规则性问题的应用。

In this paper, we first obtain the precise values of the univalent radius and the Bloch constant for harmonic mappings of the form (L(f) = z{f_z} - bar z{f_{bar z}}), where f represents normalized harmonic mappings with bounded dilation. Then, using these results, we present better estimations for the Bloch constants of certain harmonic mappings L(f), where f is a K-quasiregular harmonic or open harmonic. Finally, we establish three versions of Bloch-Landau type theorem for biharmonic mappings of the form L(f). These results are sharp in some given cases and improve the related results of earlier authors.
本文首先得到了形式为(L(f) = z{f_z} - bar z{f_{bar z}})的调和映射的一元半径和Bloch常数的精确值，其中f表示有界膨胀的归一化调和映射。然后，利用这些结果，我们给出了某些调和映射L(f)的Bloch常数的更好估计，其中f是k -准正则调和或开调和。最后，我们建立了三种形式为L(f)的双调和映射的Bloch-Landau型定理。这些结果在某些特定情况下是尖锐的，并且改进了早期作者的相关结果。

In this paper, we consider entire solutions of higher order homogeneous differential equations with the entire coefficients having the same order, and prove that the entire solutions are of infinite lower order. The properties on the radial distribution, the limit direction of the Julia set and the existence of a Baker wandering domain of the entire solutions are also discussed.

Motivated by recent advances made in the study of dividend control and risk management problems involving the U.S. bankruptcy code, in this paper we follow [44] to revisit the De Finetti dividend control problem under the reorganization process and the regulator’s intervention documented in U.S. Chapter 11 bankruptcy. We do this by further accommodating the fixed transaction costs on dividends to imitate the real-world procedure of dividend payments. Incorporating the fixed transaction costs transforms the targeting optimal dividend problem into an impulse control problem rather than a singular control problem, and hence computations and proofs that are distinct from [44] are needed. To account for the financial stress that is due to the more subtle concept of Chapter 11 bankruptcy, the surplus process after dividends is driven by a piece-wise spectrally negative Lévy process with endogenous regime switching. Some explicit expressions of the expected net present values under a double barrier dividend strategy, new to the literature, are established in terms of scale functions. With the help of these expressions, we are able to characterize the optimal strategy among the set of admissible double barrier dividend strategies. When the tail of the Lévy measure is log-convex, this optimal double barrier dividend strategy is then verified as the optimal dividend strategy, solving our optimal impulse control problem.

Clifford analysis is an important branch of modern analysis; it has a very important theoretical significance and application value, and its conclusions can be applied to the Maxwell equation, Yang-Mill field theory, quantum mechanics and value problems. In this paper, we first give the definition of a quasi-Cauchy type integral in complex Clifford analysis, and get the Plemelj formula for it. Second, we discuss the Hölder continuity for the Cauchy-type integral operators with values in a complex Clifford algebra. Finally, we prove the existence of solutions for a class of linear boundary value problems and give the integral representation for the solution.
