    A complexity trichotomy for approximately counting list H-colourings by Goldberg, L, Galanis, A, Jerrum, M

    Published 2016
    “…Two pleasing features of the trichotomy are (i) it has a natural formulation in terms of hereditary graph classes, and (ii) the proof is largely self-contained and does not require any universal algebra (unlike similar dichotomies in the weighted case). …”

    Reticulation of Quasi-commutative Algebras by G. Georgescu

    Published 2023-05-01
    “…The first systematic study of this spectrum can be found in a paper by Agliano, published in Universal Algebra (1993).The reticulation of an algebra $A\in \mathcal{V}$ is a bounded distributive algebra $L(A)$, whose prime spectrum (endowed with the Stone topology) is homeomorphic to $Spec(A)$ (endowed with the topology defined by Agliano). …”

    Constructing Higher Inductive Types as Groupoid Quotients by Niccolò Veltri, Niels van der Weide

    Published 2021-04-01
    “…We also start the development of universal algebra in 1-types. We show that the bicategory of algebras has PIE limits, i.e. products, inserters and equifiers, and we prove a version of the first isomorphism theorem for 1-types. …”

    Coalgebras for Bisimulation of Weighted Automata over Semirings by Purandar Bhaduri

    Published 2023-01-01
    “…The key step in our work is generalizing the notions of linear relation and linear bisimulation of Boreale from vector spaces to semimodules using the concept of the kernel of a $K$-linear map in the sense of universal algebra. We also provide an abstract procedure for forward partition refinement for computing weighted language equivalence. …”

    Criterion for the cosemanticness of the Abelian groups in the enriched signature by A.R. Yeshkeyev, M.T. Kassymetova, O.I. Ulbrikht

    Published 2018-03-01

    Meaning and duality: from categorical logic to quantum physics by Maruyama, Y

    Published 2016

    Configurations in abelian categories. III. Stability conditions and identities by Joyce, D

    Published 2004
    “…These encode facts about, for example, the Euler characteristic of the family of ways of decomposing a t-semistable object into t-stable factors, and constitute a kind of "universal algebra of t-(semi)stability". Using these we define interesting (Lie) algebras of constructible functions H^{pa}_t,H^{to}_t and L^{pa}_t,L^{to}_t on Obj_A. …”

    Imbrication algebras -- algebraic structures of nesting order by Ioachim M. Drugus, Volodymyr G. Skobelev

    Published 2018-11-01

    INVESTIGATION OF PROCEDURAL RELATIONSHIP BETWEEN ACADEMIC ACHIEVEMENT AND PSYCHOSOCIAL FACTORS IN ALGEBRA COURSES by Erdem DEMİRÖZ

    Published 2021-12-01
    “…In this manuscript, in addition to the psychosocial factors of mathematics learning, mathematics achievement in the context of university algebra was also examined. The data related to the psychosocial variables were obtained from a likert scale developed by the researcher, and academic achievement data from the final exam grades of the algebra course. …”
