Ray-Knight compactification of birth and death processes
Liping Li
A birth and death process is a continuous-time Markov chain with the minimal state space , whose transition matrix is standard and whose density matrix is the given birt…
Flat model structures and Gorenstein objects in functor categories
Zhenxing Di, Liping Li, Li Liang +1
We construct a flat model structure on the category of additive functors from a small preadditive category satisfying certain conditi…
Representations over diagrams of abelian categories I: Global structure and homological objects
Zhenxing Di, Liping Li, Li Liang +1
Representations over diagrams of abelian categories unify quite a few notions appearing widely in literature such as representations of categories, presheaves of modules over categ…
On diffusions with discontinuous scales
Liping Li
It is well known that a regular diffusion on an interval without killing inside is uniquely determined by a canonical scale function and a canonical speed measure . Note…
On order isomorphisms intertwining semigroups for Dirichlet forms
Liping Li, Hanlai Lin
This paper is devoted to characterizing the so-called order isomorphisms intertwining the -semigroups of two Dirichlet forms. We first show that every unitary order isomorphis…
On structure of -harmonic functions for one-dimensional diffusions
Liping Li
In this note we analyse the harmonic functions in -sense for an irreducible diffusion on an interval.
Generalizing Dirichlet-to-Neumann operators
Liping Li
The aim of this paper is to study the Dirichlet-to-Neumann operators in the context of Dirichlet forms and especially to figure out their probabilistic counterparts. Regarding irre…
