The PBW Filtration, Demazure Modules and Toroidal Current Algebras [PDF]
Let L be the basic (level one vacuum) representation of the affine Kac-Moody Lie algebra ^g. The m-th space F_m of the PBW filtration on L is a linear span of vectors of the form x_1dots x_lv_0, where l ≤ m, x_i in ^g and v_0 is a highest weight vector ...

p-Brane superalgebras via integrability
It has long been appreciated that superalgebras with bosonic and fermionic generators additional to those in the super-Poincare algebra underlie p-brane and D-brane actions in superstring theory.

The algebra generated by the down and up operators on a differential partially ordered set (poset) encodes essential enumerative and structural properties of the poset. Motivated by the algebras generated by the down and up operators on posets, we introduce here a family of infinite-dimensional associative algebras called down-up algebras. We show that

Neutrosophic Vague Binary BCK/BCI-algebra [PDF]
Ineradicable hindrances of the existing mathematical models widespread from probabilities to soft sets. These difficulties made up way for the opening of “neutrosophic set model’.

INJECTIVE MODULES OVER DOWN-UP ALGEBRAS [PDF]
AbstractThe purpose of this paper is to study finiteness conditions on injective hulls of simple modules over Noetherian down-up algebras. We will show that the Noetherian down-up algebras A(α, β, γ) which are fully bounded are precisely those which are module-finite over a central subalgebra.

Inverse Kinematics for Industrial Robots using Conformal Geometric Algebra [PDF]
This paper shows how the recently developed formulation of conformal geometric algebra can be used for analytic inverse kinematics of two six-link industrial manipulators with revolute joints.

Noetherian down-up algebras [PDF]
Down-up algebras A = A ( α , β , γ ) A= A(\alpha ,\beta ,\gamma ) were introduced by G. Benkart and T. Roby to better understand the structure of certain posets. In this paper, we prove that β ≠ 0 \beta \neq 0 is equivalent to
