Contracting and Involutive Negations of Probability Distributions
Mathematics, 2021 A dozen papers have considered the concept of negation of probability distributions (pd) introduced by Yager. Usually, such negations are generated point-by-point by functions defined on a set of probability values and called here negators.

Implicator-Conjunctor Based Models of Fuzzy Rough Sets: Definitions and Properties [PDF]
, 2016 Ever since the first hybrid fuzzy rough set model was pro- posed in the early 1990¿s, many researchers have focused on the definition of the lower and upper approximation of a fuzzy set by means of a fuzzy relation.

Reducing fuzzy answer set programming to model finding in fuzzy logics [PDF]
, 2011 In recent years, answer set programming (ASP) has been extended to deal with multivalued predicates. The resulting formalisms allow for the modeling of continuous problems as elegantly as ASP allows for the modeling of discrete problems, by combining the

Derived categories of hearts on Kuznetsov components
Journal of the London Mathematical Society, Volume 108, Issue 6, Page 2146-2174, December 2023., 2023 Abstract We prove a general criterion that guarantees that an admissible subcategory K$\mathcal {K}$ of the derived category of an abelian category is equivalent to the bounded derived category of the heart of a bounded t‐structure. As a consequence, we show that K$\mathcal {K}$ has a strongly unique dg enhancement, applying the recent results of ...

Proceedings of the London Mathematical Society, Volume 127, Issue 5, Page 1451-1506, November 2023., 2023 Abstract We establish a formula for the L‐theory spectrum of real C∗$C^*$‐algebras from which we deduce a presentation of the L‐groups in terms of the topological K‐groups, extending all previously known results of this kind. Along the way, we extend the integral comparison map τ:k→L$\tau \colon \mathrm{k}\rightarrow \mathrm{L}$ obtained in previous ...

A comprehensive study of implicator-conjunctor based and noise-tolerant fuzzy rough sets: definitions, properties and robustness analysis [PDF]
, 2015 © 2014 Elsevier B.V. Both rough and fuzzy set theories offer interesting tools for dealing with imperfect data: while the former allows us to work with uncertain and incomplete information, the latter provides a formal setting for vague concepts. The two

Stability conditions on Kuznetsov components of Gushel–Mukai threefolds and Serre functor
Mathematische Nachrichten, Volume 296, Issue 7, Page 2975-3002, July 2023., 2023 Abstract We show that the stability conditions on the Kuznetsov component of a Gushel–Mukai threefold, constructed by Bayer, Lahoz, Macrì and Stellari, are preserved by the Serre functor, up to the action of the universal cover of GL2+(R)$\text{GL}^+_2(\operatorname{\mathbb {R}})$.

Commuting varieties and cohomological complexity theory
Journal of the London Mathematical Society, Volume 106, Issue 4, Page 2847-2883, December 2022., 2022 Abstract In this paper we determine, for all r$r$ sufficiently large, the irreducible component(s) of maximal dimension of the variety of commuting r$r$‐tuples of nilpotent elements of gln$\mathfrak {gl}_n$. Our main result is that in characteristic ≠2,3$\ne 2,3$, this nilpotent commuting variety has dimension (r+1)⌊n24⌋$(r+1)\lfloor \frac{n^2}{4 ...

Patchworking oriented matroids
Journal of the London Mathematical Society, Volume 106, Issue 4, Page 3545-3576, December 2022., 2022 Abstract In a previous work, we gave a construction of (not necessarily realisable) oriented matroids from a triangulation of a product of two simplices. In this follow‐up paper, we use a combinatorial analogue of Viro's patchworking to derive a topological representation of the oriented matroid directly from the polyhedral structure of the ...

IET Power Electronics, Volume 15, Issue 14, Page 1490-1501, 4 November 2022., 2022 Abstract In the dual‐motor servo system driven by permanent magnet linear synchronous motor, a synchronous control strategy based on coupling parameter identification algorithm and feedback linearization decoupling controller is proposed to overcome the influence of mechanical coupling on the synchronous control performance of the system.
