On Multilevel Energy‐Based Fragmentation Methods
International Journal of Quantum Chemistry, Volume 126, Issue 3, February 5, 2026.We investigate the working equations of energy‐based fragmentation methods and present ML‐SUPANOVA, a Möbius‐inversion‐based multilevel fragmentation scheme that enables adaptive, quasi‐optimal truncations to efficiently approximate Born‐Oppenheimer potentials across hierarchies of electronic‐structure methods and basis sets.

Generating functions on idempotent semigroups. II. Semilattice variables and independence [PDF]
, 1972 In earlier work it was shown that if two functions in the algebra of functions of single semilattice elements were convolved then the generating function of the convolution was the pointwise product of the generating functions of the functions convolved.

Semigroup of k-bi-Ideals of a Semiring with Semilattice Additive Reduct
Demonstratio Mathematica, 2016 We associate a semigroup B(S) to every semiring S with semilattice additive reduct, namely the semigroup of all k-bi-ideals of S; and such semirings S have been characterized by this associated semigroup B(S). A semiring S is k-regular if and only if B(S)

Corrigendum to “Perfect semilattices” [PDF]
Semigroup Forum, 1985 B. M. Schein let us know that \(S_ 3\) is not perfect. In fact, it is the smallest non-perfect semilattice. Consequently, Theorem 1 of the paper mentioned in the title [ibid. 32, 23-29 (1985; Zbl 0564.06004)] has to be corrected as follows. Let S be a semilattice. Then the following are equivalent: (1) S is perfect; (4) S is a chain.

Some Properties of Hyper Ideals in Hyper Hoop‐Algebras
Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.In this paper, we investigate the structural properties of hyper ideals in hyper hoop‐algebras, a generalization of hoop‐algebras under the framework of hyperstructures. Building upon foundational concepts in hyper group theory and hoop theory, the study introduces definitions for hyper ideals and weak hyper ideals, as well as their absorptive and ...

基本弱Hopf代数和弱覆盖箭图(Basic weak Hopf algebra and weak covering quiver)
Zhejiang Daxue xuebao. Lixue ban, 2016 We introduce a finite-dimensional basic and split weak Hopf algebra H over an algebraically closed field k with strongly graded Jacobson radical r. We obtain some structures of a finite-dimensional basic and split semilattice graded weak Hopf algebra,and

Relatively pseudocomplemented posets [PDF]
Mathematica Bohemica, 2018 We extend the notion of a relatively pseudocomplemented meet-semilattice to arbitrary posets. We show some properties of the binary operation of relative pseudocomplementation and provide some corresponding characterizations.

Simplicial homology and Hochschild cohomology of Banach semilattice algebras [PDF]
, 2006 The $\ell^{1}$-convolution algebra of a semilattice is known to have trivial cohomology in degrees 1, 2 and 3 whenever the coefficient bimodule is symmetric.

$0$-ideals in $0$-distributive posets [PDF]
Mathematica Bohemica, 2016 The concept of a $0$-ideal in $0$-distributive posets is introduced. Several properties of $0$-ideals in $0$-distributive posets are established. Further, the interrelationships between $0$-ideals and $\alpha$-ideals in $0$-distributive posets are ...
