  • A cottage industry of lax extensions 

    Hofmann, Dirk؛ Seal, Gavin J. (Shahid Beheshti University, 2015-07-01)
    In this work, we describe an adjunction between the comma category of Set-based monads under the V -powerset monad and the category of associative lax extensions of Set-based monads to the category of V -relations. In the ...

  • $omega$-Operads of coendomorphisms and fractal $omega$-operads for higher structures 

    Kachour, Camell (Shahid Beheshti University, 2015-07-01)
    In this article we introduce the notion of textit{Fractal $omega$-operad} emerging from  a natural $omega$-operad associated to any coglobular object in the category of higher operads in Batanin's sense, which in fact is ...

  • Order dense injectivity of $S$-posets 

    Shahbaz, Leila (Shahid Beheshti University, 2015-07-01)
    ‎‎‎In this paper‎, ‎the‎ notion of injectivity with respect to order dense embeddings in ‎‎the category of $S$-posets‎, ‎posets with a monotone action of a‎ pomonoid $S$ on them‎, ‎is studied‎. ‎We give a criterion‎, ‎like ...

  • Actions of a separately strict cpo-monoid on pointed directed complete posets 

    Moghbeli Damaneh, Halimeh (Shahid Beheshti University, 2015-07-01)
    ‎ In the present article‎, ‎we study some categorical properties of the category {$bf‎ Cpo_{Sep}$-$S$} of all {separately strict $S$-cpo's}; cpo's equipped with‎ a compatible right action of a separately strict cpo-monoid ...

  • Subpullbacks and coproducts of $S$-posets 

    Liang, Xingliang؛ Luo, Yanfeng (Shahid Beheshti University, 2015-07-01)
    In 2001, S. Bulman-Fleming et al. initiated the study of three flatness properties (weakly kernel flat, principally weakly kernel flat, translation kernel flat) of right acts $A_{S}$ over a monoid $S$ that can be described ...
