Complements of intervals and prefrattini subalgebras of solvable Lie algebras. [PDF]

, 2013
In this paper we study a Lie-theoretic analogue of a generalisation of the prefrattini subgroups introduced by W. Gasch¨utz. The approach follows that of P. Hauck and H.

On semi-modular subalgebras of Lie algebras over fields of arbitrary characteristic. [PDF]

, 2008
This paper is a further contribution to the extensive study by a number of authors of the subalgebra lattice of a Lie algebra. It is shown that, in certain circumstances, including for all solvable algebras, for all restricted Lie algebras over ...

On Lie algebras all of whose minimal subalgebras are lower modular. [PDF]

, 2004
The main purpose of this paper is to study Lie algebras L such that if a subalgebra U of L has a maximal subalgebra of dimension one then every maximal subalgebra of U has dimension one. Such an L is called lm(0)-algebra.

Almost nilpotent Lie algebras [PDF]

, 1987
Throughout we shall consider only finite-dimensional Lie algebras over a field of characteristic zero. In [3] it was shown that the classes of solvable and of supersolvable Lie algebras of dimension greater than two are characterised by the structure of ...

Pseudo-differential equations, and the Bethe ansatz for the classical Lie algebras [PDF]

, 2007
The correspondence between ordinary differential equations and Bethe ansatz equations for integrable lattice models in their continuum limits is generalised to vertex models related to classical simple Lie algebras.

Implicative algebras and Heyting algebras can be residuated lattices [PDF]

, 2017
The commutative residuated lattices were first introduced by M. Ward and R.P. Dilworth as generalization of ideal lattices of rings. Complete studies on residuated lattices were developed by H. Ono, T. Kowalski, P. Jipsen and C. Tsinakis.

Topos-Theoretic Approaches to Quantum Theory [PDF]

, 2012
Starting from a naive investigation into the nature of experiments on a physical system one can argue that states of the system should pair non-degenerately with physical observables. This duality is closely related to that between space and quantity, or,

The variety generated by order algebras [PDF]

, 2002
Every ordered set can be considered as an algebra in a natural way. We investigate the variety generated by order algebras. We prove, among other things, that this variety is not finitely based and, although locally finite, it is not contained in any ...

Etale algebras over finite Heyting algebras [PDF]

In this paper, we investigate the concept of local homeomorphism in Esakia spaces. We introduce the notion of etale Heyting H-algebra and establish category-theoretic duality for etale Heyting H-algebra in the case of finite Heyting algebra H ...

Dual intuitionistic logic and Co-Heyting algebras

, 2009
Presentamos ejemplos de álgebras de Heyting, co-Heyting y bi-Heyting y relaciones con las lógicas intuicionista, dual-intuicionista y bi-intuicionista. Estudiamos los operadores modales descritos en Reyes and Zolfaghari, 1996. Finalmente, indicamos una
