## Abstract We define the set of double complemented elements in BL‐algebras and state and prove some theorems which determines properties of these sets. We introduce the notion of an almost top element and study the properties of these elements (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

✍ Somayeh Motamed; Lida Torkzadeh; Arsham Borumand Saeid; Neda Mohtashamnia 📂 Article 📅 2011 🏛 John Wiley and Sons 🌐 English ⚖ 138 KB

In this paper, the notion of the radical of a filter in BL-algebras is defined and several characterizations of the radical of a filter are given. Also we prove that A/F is an M V -algebra if and only if Ds (A) ⊆ F . After that we define the notion of semi maximal filter in BL-algebras and we state

n -fold filters in BL-algebras

✍ Masoud Haveshki; Esfandiar Eslami 📂 Article 📅 2008 🏛 John Wiley and Sons 🌐 English ⚖ 112 KB

## Abstract In this paper we introduce __n__ ‐fold (positive) implicative basis logic and the related algebras called __n__ ‐fold (positive) implicative BL‐algebras. Also we define __n__ ‐fold (positive) implicative filters and we prove some relations between these filters and construct quotient al

Finiteness results in n-homotopy theory

✍ A. Chigogidze; K. Kawamura; R.B. Sher 📂 Article 📅 1996 🏛 Elsevier Science 🌐 English ⚖ 789 KB

We establish some finiteness results in the n-homotopy category. These results, unlike the corresponding ones in the "ordinary" homotopy category, do not involve algebraic obstructions.
