Universal quadratic forms and Northcott property of infinite number fields
Journal of the London Mathematical Society, Volume 110, Issue 5, November 2024.Abstract We show that if a universal quadratic form exists over an infinite degree, totally real extension of the field of rationals Q$\mathbb {Q}$, then the set of totally positive integers in the extension does not have the Northcott property. In particular, this implies that no universal form exists over the compositum of all totally real Galois ...

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.By relying on the foundation engineering of pile foundations for the Chengdu Metro Line 27 shield tunneling through interchange bridges, three‐dimensional numerical simulation results are used to verify field measurements. This study investigates the horizontal displacement, vertical displacement, and stress characteristics of the pile foundation ...

Ordered Left Almost ⋇‐Semihypergroups Based on Fuzzy Sets
Journal of Mathematics, Volume 2024, Issue 1, 2024.The concept of an involution or anti‐involution is a self‐inverse linear mapping that plays a prominent role in the theory of algebraic structures, particularly rings, hyperrings, ordered semigroups, and ordered semihypergroups. Nowadays, the study of involutions in ordered hyperstructures is a particular area of research in the field of hyperstructure

Q-FUZZY IDEAL OF ORDERED Γ-SEMIRING
Journal of New Theory, 2015 − The notion of Q-fuzzy ideal in ordered Γ-semiring is introduced and studied along withsome operations. Among all other results, it is shown that the set of all Q-fuzzy ideals of a Γ-semiringforms a complete lattice.

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.The isogeometric (IG) Reissner–Mindlin (R–M) shell model solves the problem of shear and membrane locking that besets the finite element (FE) R–M shell model of nonthick underground structures, but still faces complicated modeling and computation, especially for the multijoint structures.

Timed Soft Concurrent Constraint Programs: An Interleaved and a Parallel Approach
, 2014 We propose a timed and soft extension of Concurrent Constraint Programming. The time extension is based on the hypothesis of bounded asynchrony: the computation takes a bounded period of time and is measured by a discrete global clock.

(λ,μ)-FUZZY IDEALS OF ORDERED Γ-SEMIRINGS
Journal of New Theory, 2016 Abstaract−The notions of (λ, µ)-fuzzy ideals, (λ, µ)-fuzzy k-ideals, (λ, µ)-fuzzy k-bi-ideals, (λ, µ)-fuzzy k-quasi-ideals of an ordered Γ-semirings are introduced and some related properties are investigated.

Processing Succinct Matrices and Vectors
, 2014 We study the complexity of algorithmic problems for matrices that are represented by multi-terminal decision diagrams (MTDD). These are a variant of ordered decision diagrams, where the terminal nodes are labeled with arbitrary elements of a semiring ...
