Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Regularity of sub-elliptic harmonic map into non-positively curved metric space
亚椭圆谐波 非正曲线 度量空间 规律性
font style='font-size:12px;'>
2023/4/28
We prove the Holder continuity of a harmonic map from a domain of a sub-Riemannian manifold into a locally compact manifold with non-positive curvature, and more generally into a non-positively curved...
On character of points in the Higson corona of a metric space
Higson corona character of a point ultrafilter number dominating number

2012/6/19
We prove that for an unbounded metric space $X$, the minimal character $m\chi(\check X)$ of a point of the Higson corona $\check X$ of $X$ is equal to $\mathfrak u$ if $X$ has asymptotically isolated ...
Ekeland's Variational Principle for An $\bar{L}^{0}-$Valued Function on A Complete Random Metric Space
Random metric space random normed module L0− valued function lower semicontinuity Ekeland’s variational principle

2011/9/20
Abstract: Motivated by the recent work on conditional risk measures, this paper studies the Ekeland's variational principle for a proper, lower semicontinuous and lower bounded $\bar{L}^{0}-$valued fu...
The Muckenhoupt $A_\infty$ class as a metric space and continuity of weighted estimates
Calderon–Zygmund operators A2 weights interpolation

2011/8/25
Abstract: We show how the $A_\infty$ class of weights can be considered as a metric space. As far as we know this is the first time that a metric d is considered on this set. We use this metric to gen...
Systems of dyadic cubes in a doubling metric space
Space of homogeneous type dyadic cube random geometric construction
font style='font-size:12px;'>
2011/1/20
A number of recent results in Euclidean Harmonic Analysis have exploited several adjacent systems of dyadic cubes, instead of just one fixed system. In this paper, we extend such constructions to gene...

dislocated quasi-metric fixed point
font style='font-size:12px;'>
2010/9/20
In this paper we have proved fixed point theorems for continuous contraction mappings in dislocated quasi-metric space. Also we obtain a common fixed point theorem for a pairs of mappings in dislocate...
Non-local PDEs with discrete state-dependent delays: well-posedness in a metric space
Non-local PDEs discrete state-dependent delays metric space
font style='font-size:12px;'>
2010/11/17
Partial differential equations with discrete (concentrated) state-dependent delays are studied. The existence and uniqueness of solutions with initial data from a wider linear space is proven first a...

2010/11/12
In this paper, first we have established two sets of sufficient conditions for a mapping to have unique fixed point in a intuitionistic fuzzy metric space and then we have redefined the contraction ma...

In this article, some new completeness theorems in probabilis-
tic normed space are proved. Moreover, the existence of a constrictive
Menger probabilistic normed space is shown.

font style='font-size:12px;'>
2010/2/26
Variety of Banach algebras is a non-empty class of Banach algebras in which there exist a family of laws such that all of its members satisfy all of the laws. In this paper, we have used merely mathem...
Best p-Simultaneous Approximation in Some Metric Space
Simultaneous Approximation

2010/2/25
Let X be a Banach space, (I,m) be a finite measure space, and F be an increasing subadditive continuous function on [0,+\infty) with F(0)=0. In the present paper, we discuss the best p-simultaneous ap...
