Automatically Building and Updating a Knowledge Graph of MLIP Models

Alexis Beer, Liudmyla Klochko, Mathieu d'Aquin

Complementing the many efforts in providing semantic representations of concepts, notions, and entities in materials science, we report and illustrate a process by which we can aut…

Tilting Completion and Full-Rank Self-Orthogonal Modules

Wen Chang, Quanyu Tang

We give negative answers to two tilting-completion questions for finite-dimensional algebras. We construct two finite-dimensional basic connected quasi-hereditary -algeb…

Infinitely Many Components in Auslander--Reiten Quivers of Representation-Infinite Algebras over Perfect Fields

Wen Chang, Quanyu Tang

Let be a perfect field and let be a representation-infinite finite-dimensional -algebra. We prove that the Auslander--Reiten quiver of has infinitely many connected…

Geometric models for the algebraic hearts in the derived category of a gentle algebra

Wen Chang

We give a geometric model for any algebraic heart in the derived category of a gentle algebra, which is equivalent to the module category of some gentle algebra. To do this, we def…

Quasi-homomorphisms of quantum cluster algebras

Wen Chang, Min Huang, Jian-Rong Li

In this paper, we study quasi-homomorphisms of quantum cluster algebras, which are quantum analogy of quasi-homomorphisms of cluster algebras introduced by Fraser. For a quantum Gr…

Braid group actions on branched coverings and full exceptional sequences

Wen Chang, Fabian Haiden, Sibylle Schroll

We relate full exceptional sequences in Fukaya categories of surfaces or equivalently in derived categories of graded gentle algebras to branched coverings over the disk, building…

Geometric model for module categories of Dynkin quivers via hearts of total stability conditions

Wen Chang, Yu Qiu, Xiaoting Zhang

We derive a geometric model for the module category of a Dynkin quiver via the heart of a total stability condition on the bounded derived cat…

Recollements of partially wrapped Fukaya categories and surface cuts

Wen Chang, Haibo Jin, Sibylle Schroll

In this paper we use recollements to investigate partially wrapped Fukaya categories of surfaces with marked points. In particular, we show that cutting surfaces gives rise to reco…

Exceptional sequences in the derived category of a gentle algebra

Wen Chang, Sibylle Schroll

In this paper, using the correspondence of gentle algebras and dissections of marked surfaces, we study full exceptional sequences in the perfect derived category …

A geometric realization of silting theory for gentle algebras

Wen Chang, Sibylle Schroll

A gentle algebra gives rise to a dissection of an oriented marked surface with boundary into polygons and the bounded derived category of the gentle algebra has a geometric interpr…

Quivers with potentials for Grassmannian cluster algebras

Wen Chang, Jie Zhang

We consider (iced) quiver with potential associated to a Postnilov Diagram and prove the mutation of the quiver with potential $(\bare{Q}(D), F…

Quantum affine algebras and Grassmannians

Wen Chang, Bing Duan, Chris Fraser +1

We study the relation between quantum affine algebras of type A and Grassmannian cluster algebras. Hernandez and Leclerc described an isomorphism from the Grothendieck ring of a ce…

A note on cluster automorphism groups

Wen Chang, Ralf Schiffler

We conjecture a characterization of a cluster automorphism as an algebra homomorphism from the cluster algebra to itself that restricts to a bijection between two clusters. This fo…

Cluster automorphisms and quasi-automorphisms

Wen Chang, Ralf Schiffler

We study the relation between the cluster automorphisms and the quasi-automorphisms of a cluster algebra . We proof that under some mild condition, satisfied for examp…

Cluster subalgebras and cotorsion pairs in Frobenius extriangulated categories

Wen Chang, Panyue Zhou, Bin Zhu

Nakaoka and Palu introduced the notion of extriangulated categories by extracting the similarities between exact categories and triangulated categories. In this paper, we study cot…

Cluster automorphism groups of cluster algebras with coefficients

Wen Chang, Bin Zhu

We study the cluster automorphism group of a skew-symmetric cluster algebra with geometric coefficients. For this, we introduce the notion of gluing free cluster algebra, and show…

On rooted cluster morphisms and cluster structures in -Calabi-Yau triangulated categories

Wen Chang, Bin Zhu

We study rooted cluster algebras and rooted cluster morphisms which were introduced in \cite{ADS13} recently and cluster structures in -Calabi-Yau triangulated categories. An ex…
