Geometric Realizations of Capability Spaces of Large Models and Zigzag Persistent Homology

Yu-Zhe Liu, Shengda Liu, Jianyong Pi +1

We propose a topological model for capability changes during large-model training. The model represents knowledge states and preregistered capability probes as subcomplexes of a fi…

Module-valued ordinary differential equations and structure of solution spaces

Shengda Liu, Yu-Zhe Liu, Keyu Tao

We define and study ordinary differential equations (ODEs) for functions valued in a Banach module over a finite-dimensional -algebra by using the tensor of B…

Igusa-Todorov properties of recollements of abelian categories

Peiru Yang, Yajun Ma, Yu-Zhe Liu

In this paper, we investigate the behavior of Igusa-Todorov properties under recollements of abelian categories. In particular, we study how the Igusa-Todorov distances of the cate…

Normed representations of weight quivers

Yu-Zhe Liu

Let and be two tensor rings given by weight quivers. We introduce norms for tensor rings and -bimodules, and define an important category in this p…

Some functors preserving exceptionality

Dajun Liu, Hanpeng Gao, Yu-Zhe Liu

We constructed some tensor functors that send each exceptional sequence in a module category to another exceptional sequence in another module category by using split extensions an…

On BD-algebra and CM-Auslander algebra for a gentle algebra and their representation types

Mengdie Zhang, Yu-Zhe Liu, Chao Zhang

Let be a gentle algebra, and and be its BD-gentle algebra and CM-Auslander algebra, respectively. In this paper, we show that the representation-finiteness of , …

Homological dimensions over almost gentle algebras

Demin Wang, Zhaoyong Huang, Yu-Zhe Liu

We provide a method for computing the global dimension and self-injective dimension of almost gentle algebras,and prove that an almost gentle algebra is Gorenstein if it satisfies…

Normed modules, integral sequences, and integrals with variable upper limits

Miantao Liu, Yu-Zhe Liu, Shengda Liu

This paper provides a new categorification of the Lebesgue integral with variable upper limits by using normed modules over finite-dimensional -algebras and the c…

Three homological invariants under cleft extensions

Yajun Ma, Junling Zheng, Yu-Zhe Liu

In this paper, we investigate the behavior of Igusa-Todorov distances, extension and Rouquier dimensions under cleft extensions of abelian categories. We apply our results to Morit…

Normed modules and The Stieltjes integrations of functions defined on finite-dimensional algebras

Hanpeng Gao, Shengda Liu, Yu-Zhe Liu +1

We define integrals for functions on finite-dimensional algebras, adapting methods from Leinster's research. This paper discusses the relationships between the integrals of functio…

A negative answer to Complement Question for presilting complexes

Yu-Zhe Liu, Yu Zhou

In this paper using a geometric model we show that there is a presilting complex over a finite dimensional algebra, which is not a direct summand of a silting complex.

There are no strictly shod algebras in hereditary gentle algebras

Houjun Zhang, Yu-Zhe Liu

We prove that there are no strictly shod algebras in hereditary gentle algebras by geometric models. As an application, we give a classification of the silted algebras for Dynkin t…
