Finite dimensionality of Besov spaces and potential-theoretic decomposition of metric spaces

Takashi Kumagai, Nageswari Shanmugalingam, Ryosuke Shimizu

In the context of a metric measure space , we explore the potential-theoretic implications of having a finite-dimensional Besov space. We prove that if the dimension of th…

On Kigami's conjecture of the embedding

Shiping Cao, Zhen-Qing Chen, Takashi Kumagai

Let be a connected compact metric space and . Under the assumption of \cite[Assumption 2.15]{Ki2} and the conductive -homogeneity, we show that $\mathc…

Quantitative stochastic homogenization for random conductance models with stable-like jumps

Xin Chen, Zhen-Qing Chen, Takashi Kumagai +1

We consider random conductance models with long range jumps on , where the one-step transition probability from to is proportional to with $α\in…

Limit theorems for some long range random walks on torsion free nilpotent groups

Zhen-Qing Chen, Takashi Kumagai, Laurent Saloff-Coste +2

We consider a natural class of long range random walks on torsion free nilpotent groups and develop limit theorems for these walks. Given the original discrete group and a rand…

Spectral dimension of simple random walk on a long-range percolation cluster

Van Hao Can, David A. Croydon, Takashi Kumagai

Consider the long-range percolation model on the integer lattice in which all nearest-neighbour edges are present and otherwise and are connected with probab…

Heat kernels for reflected diffusions with jumps on inner uniform domains

Zhen-Qing Chen, Panki Kim, Takashi Kumagai +1

In this paper, we study sharp two-sided heat kernel estimates for a large class of symmetric reflected diffusions with jumps on the closure of an inner uniform domain in a leng…
