Energy Science &Engineering, EarlyView.ABSTRACT This study investigates double‐diffusive transport and entropy generation in a wavy cylindrical enclosure containing Cu─H2O Casson nanofluid under magnetic field and thermal radiation effects. The governing equations were solved numerically using the finite element method with Galerkin formulation.

Solvability of a Bounded Parametric System in Max-Łukasiewicz Algebra
Mathematics, 2020 The max-Łukasiewicz algebra describes fuzzy systems working in discrete time which are based on two binary operations: the maximum and the Łukasiewicz triangular norm.

Some Results about Triangular Representations of Lie Algebras [PDF]
arXiv, 2014 We introduce the concept of a triangular representation of a Lie algebra, give a counterpart of Ado's theorem, and discuss $2$-irreducible triangular modules over a nonreductive Lie algebra.

On Hopf algebras with triangular decomposition
, 2018 In this survey, we first review some known results on the representation theory of algebras with triangular decomposition, including the classification of the simple modules. We then discuss a recipe to construct Hopf algebras with triangular decomposition.

Jordan maps on triangular algebras
Linear Algebra and its Applications, 2007 AbstractLet T be a triangular algebra and R′ be an arbitrary ring. Suppose that M:T→R′ and M∗:R′→T are surjective maps such thatM(aM∗(x)+M∗(x)a)=M(a)x+xM(a),M∗(M(a)x+xM(a))=aM∗(x)+M∗(x)afor all a∈T,x∈R′. In this paper, we give sufficient conditions on T such that both M and M∗ are additive. In particular, if T is a standard subalgebra of a nest algebra,

Auctions versus bookbuilding: The effects of IPO regulation in Japan
Financial Review, Volume 58, Issue 1, Page 117-141, February 2023., 2023 Abstract We analyze a regulatory change in the Japanese IPO market that created an abrupt shift from hybrid price‐discriminatory auctions to bookbuilding. We find that bookbuilding leads to higher underpricing than hybrid price‐discriminatory auctions.

Characterizations of generalized Lie n-higher derivations on certain triangular algebras
AIMS MathematicsThe aim of this paper was to provide a characterization of nonlinear generalized Lie $ n $-higher derivations for a certain class of triangular algebras. It was shown that, under some mild conditions, each component $ G_r $ of a nonlinear generalized Lie

Generalized Jordan N-Derivations of Unital Algebras with Idempotents
Journal of Mathematics, 2021 Let A be a unital algebra with idempotent e over a 2-torsionfree unital commutative ring ℛ and S:A⟶A be an arbitrary generalized Jordan n-derivation associated with a Jordan n-derivation J.

Triangular Decomposition of the Composition Algebra of the Kronecker Algebra
Journal of Algebra, 1996 AbstractLetAbe a finite-dimensional hereditary algebra over a finite field, and letH(A) andC(A) be, respectively, the Ringel–Hall algebra and the composition algebra ofA. Definerdto be the element ∑[M]∈H(A), where [M] runs over the isomorphism classes of the regularA-modules with dimension vectord.
