Vladimir Arnold defined three invariants for generic planar immersions, i.e. planar curves whose self-intersections are all transverse double points. We use a variational approach to study these invariants by investigating a suitably truncated knot energy, the tangent-point energy. We prove existence of energy minimizers for each truncation parameter δ>0 in a class of immersions with prescribed winding number and Arnold invariants, and establish Gamma convergence of the truncated tangent-point energies to a limiting renormalized tangent-point energy as δ0. Moreover, we show that any sequence of minimizers subconverges in C1, and the corresponding limit curve has the same topological invariants, self-intersects exclusively at right angles, and minimizes the renormalized tangent-point energy among all curves with right self-intersection angles. In addition, the limit curve is an almost-minimizer for all of the original truncated tangent-point energies as long as the truncation parameter δ is sufficiently small. Therefore, this limit curve serves as an “optimal” curve in the class of generic planar immersions with prescribed winding number and Arnold invariants.
Vladimir Arnold定义了一般平面浸入式的三个不变量,即自交均为横向双点的平面曲线。我们使用变分的方法来研究这些不变量,通过研究一个适当截断的结能量,切点能量。在给定圈数和Arnold不变量的浸入式中,证明了每一个截断参数δ>;0的能量极小值的存在性,并建立了截断的切点能量的伽玛收敛到一个极限重归一化切点能量为δ→0。此外,我们还证明了任何最小值序列在C1中都是子收敛的,并且相应的极限曲线具有相同的拓扑不变量,在直角处完全自交,并且在所有自交角为直角的曲线中极小化了的切点能量。此外,只要截断参数δ足够小,对于所有原始截断的切点能量,极限曲线几乎是最小的。因此,该极限曲线可作为具有规定圈数和阿诺德不变量的一般平面浸没的一类“最优”曲线。

We investigate the asymptotic behavior as ɛ0 of singularly perturbed phase transition models of order n2, given by Gɛλ,n[u]I1ɛW(u)λɛ2n3(u(n1))2+ɛ2n1(u(n))2dx,uWn,2(I),where λ>0 is fixed, IR is an open bounded interval, and WC0(R) is a suitable double-well potential. We find that there exists a positive critical parameter depending on W and n, such that the Γ-limit of Gɛλ,n with respect to the L1-topology is given by a sharp interface functional in the subcritical regime. The cornerstone for the corresponding compactness property is a novel nonlinear interpolation inequality involving higher-order derivatives, which is based on Gagliardo–Nirenberg type inequalities.
研究了n≥2阶奇异摄动相变模型的渐近性,其中λ λ,n[u]是∫I1 ^ W(u)−λ ^ 2n−3(u(n−1))2+ ^ 2n−1(u(n))2dx,u∈Wn,2(I),其中λ ^ gt;0是固定的,I∧R是一个开有界区间,W∈C0(R)是一个合适的双阱势。我们发现存在一个依赖于W和n的正临界参数,使得G λ,n关于l1拓扑的Γ-limit由亚临界区中的锐界面泛函给出。该紧性的基础是基于Gagliardo-Nirenberg型不等式的一种涉及高阶导数的非线性插值不等式。

We develop geometric analysis on weighted Riemannian manifolds under lower 0-weighted Ricci curvature bounds. Under such curvature bounds, we prove a first non-zero Steklov eigenvalue estimate of Wang–Xia type on compact weighted manifolds with boundary, and a first non-zero eigenvalue estimate of Choi–Wang type on closed weighted minimal hypersurfaces. We also produce an ABP estimate and a Sobolev inequality of Brendle type.

In this paper, we obtain a priori estimates for the set of anti-symmetric solutions to a fractional Laplacian equation in a bounded domain using a blowing-up and rescaling argument. In order to establish a contradiction to possible blow-ups, we apply a certain variation of the moving planes method in order to prove a monotonicity result for the limit equation after rescaling.

The Dirichlet problem on lower dimensional boundaries: Schauder estimates via perforated domains 低维边界上的Dirichlet问题:通过穿孔区域的Schauder估计

In this paper, we investigate the Dirichlet problem on lower dimensional manifolds for a class of weighted elliptic equations with coefficients that are singular on such sets. Specifically, we study the problem div(|y|aA(x,y)u)=|y|af+div(|y|aF),u=ψ,onΣ0, where (x,y)Rdn×Rn, 2nd, a+n(0,2), and Σ0={|y|=0} is the lower dimensional manifold where the equation loses uniform ellipticity.
Our primary objective is to establish C0,α and C1,α regularity estimates up to Σ0, under suitable assumptions on the coefficients and the data. Our approach combines perforated domain approximations, Liouville-type theorems and a blow-up argument.

Formation of delta shock waves in the limit of Riemann solutions to the Aw–Rascle traffic model with a damping term 带阻尼项的Aw-Rascle交通模型黎曼解极限下三角洲激波的形成

In this paper, we consider the Riemann problem of the Aw–Rascle traffic model with a damping term and the formation of delta shock waves in the limit of the Riemann solutions as γ1. By introducing a new variable and employing generalized characteristic analysis methods, we construct solutions to the Riemann problem of the inhomogeneous Aw–Rascle traffic model. Specially, for the case 0<u<u+, we prove the existence of a critical value γ¯0 for γ such that when 0<γ<γ¯0, the Riemann solutions contain no vacuum states; otherwise, a vacuum state emerges. Furthermore, we demonstrate that as γ1, the limit of the Riemann solutions with vacuum states aligns with the Riemann solutions to the inhomogeneous transport model under the same initial conditions, while the limit of solutions with shock waves converges to a curved delta shock solution. Notably, the weights supported on the delta shock solution differ from the Riemann solutions to the inhomogeneous transport model due to the influence of the damping term.
本文考虑了带阻尼项的Aw-Rascle交通模型的黎曼问题,以及黎曼解极限为γ→1时δ激波的形成。通过引入一个新的变量,利用广义特征分析方法,构造了非齐次交通模型的Riemann问题的解。特别地,对于0<;u−<;u+的情况,我们证明了γ的一个临界值γ¯0的存在性,使得当0<;γ<;γ¯0时,黎曼解不包含真空态;否则,出现真空状态。进一步证明,当γ→1时,具有真空态的黎曼解的极限与非均匀输运模型的黎曼解在相同初始条件下对准,而具有激波的黎曼解的极限收敛于弯曲的δ激波解。值得注意的是,由于阻尼项的影响,delta激波解所支持的权重与非均匀输运模型的黎曼解不同。

We show a global existence result for a doubly nonlinear porous medium type equation of the form ut=Δpum+uq on a complete and non-compact Riemannian manifold M of infinite volume. Here, for 1<p<N, we assume m(p1)1, m>1 and q>m(p1). In particular, under the assumptions that M supports the Sobolev inequality, we prove that a solution for such a problem exists globally in time provided q>m(p1)+pN and the initial datum is small enough; namely, we establish an explicit bound on the L norm of the solution at all positive times, in terms of the L1 norm of the data. Under the additional assumption that a Poincaré-type inequality also holds in M, we can establish the same result in the larger interval, i.e. q>m(p1). This result has no Euclidean counterpart, as it differs entirely from the case of a bounded Euclidean domain due to the fact that M is non-compact and has infinite measure.
在无限体积的完全非紧黎曼流形M上,给出了形式为ut=Δpum+uq的双非线性多孔介质型方程的整体存在性结果。这里,对于1<;p<;N,我们假设m(p−1)≥1,m>;1和q>;m(p−1)。特别地,在M支持Sobolev不等式的假设下,我们证明了在q>; M (p−1)+pN且初始基准足够小的情况下,该问题的解在时间上全局存在;也就是说,我们根据数据的L1范数,在所有正时刻的解的L∞范数上建立一个显式的界。在附加的假设下,一个poincar型不等式在M中也成立,我们可以在更大的区间,即q>; M (p−1)中建立同样的结果。这个结果没有欧几里得对应物,因为它完全不同于有界欧几里得定义域的情况,因为M是非紧致的并且具有无限的度量。

We prove that the Benjamin–Ono equation is globally well-posed in Hs(R) for s>12. Our approach does not rely on the global gauge transformation introduced by Tao (Tao, 2004). Instead, we employ a modified version of the standard parabolic regularization method. In particular, this technique also enables us to establish global well-posedness, in the same Sobolev space, for the dispersion-generalized Benjamin–Ono (DGBO) equation.
我们证明了对于s>;12, Benjamin-Ono方程在Hs(R)上是全局适定的。我们的方法不依赖于Tao (Tao, 2004)引入的全局规范转换。相反,我们采用标准抛物线正则化方法的改进版本。特别地,该技术还使我们能够在相同的Sobolev空间中为色散广义Benjamin-Ono (DGBO)方程建立全局适定性。
