Interior GE-Filters of GE-Algebras
Discussiones Mathematicae - General Algebra and Applications, 2022 The notions of an interior GE-filter, a weak interior GE-filter and a belligerent interior GE-filter are introduced, and their relations and properties are investigated. Example of a GE-filter which is neither an interior GE-filter nor a weak interior GE-

A Database for Field Extensions of the Rationals [PDF]
LMS J. Comput. Math., 2001 We report on a database of field extensions of the rationals, its properties and the methods used to compute it. At the moment the database encompasses roughly 100,000 polynomials generating distinct number fields over the rationals, of degrees up to 15.

2-plectic geometry, Courant algebroids, and categorified prequantization [PDF]
, 2010 A 2-plectic manifold is a manifold equipped with a closed nondegenerate 3-form, just as a symplectic manifold is equipped with a closed nondegenerate 2-form.

Elitable GE-filters of bordered GE-algebras
Soft Computing - A Fusion of Foundations, Methodologies and Applications, 2022 In this paper, the notions of maximal GE-filter and prime GE-filter of a GE-algebra are introduced and the relation between them is given. Some characterizations of prime GE-filters of a transitive GE-algebra are given in terms of the GE-filter generated

Existential Calculi of Relations with Transitive Closure: Complexity and Edge Saturations [PDF]
Logic in Computer Science, 2023 We study the decidability and complexity of equational theories of the existential calculus of relations with transitive closure (ECoR*) and its fragments, where ECoR* is the positive calculus of relations with transitive closure extended with ...

The range of operators on von Neumann algebras [PDF]
, 2001 We prove that for every bounded linear operator T: X → X, where X is a non-reflexive quotient of a von Neumann algebra, the point spectrum of T * is non-empty (i.e., for some A ∈ C the operator λI - T fails to have dense range).

Simple transitive 2-representations via (co)algebra 1-morphisms [PDF]
Indiana University Mathematics Journal, 2016 For any fiat 2-category C, we show how its simple transitive 2-representations can be constructed using coalgebra 1-morphisms in the injective abelianization of C.

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT This paper presents a robust control synthesis and analysis framework for nonlinear systems with uncertain initial conditions. First, a deep learning‐based lifting approach is proposed to approximate nonlinear dynamical systems with linear parameter‐varying (LPV) state‐space models in higher‐dimensional spaces while simultaneously ...

Limit Orders and Knightian Uncertainty
International Economic Review, EarlyView.ABSTRACT A wide variety of financial instruments allows risk‐averse traders to reduce their exposure to risk. This raises the question of what financial instruments allow ambiguity‐averse traders to reduce their exposure to ambiguity. We show in this paper that price‐contingent orders, such as limit orders, are sufficient: In a two‐period trading model,
