For two normed algebras $A$ and $B$ with the character space   $bigtriangleup(B)neq emptyset$  and a left $B-$module $X,$  a certain class of bounded linear maps from $A$ into $X$ is introduced. We set $CMH_B(A, X)$  as the set of all non-zero $B-$character module homomorphisms from $A$ into $X$. In the case where $bigtriangleup(B)=lbrace varphirbrace$ then $CMH_B(A, X)bigcup lbrace 0rbrace$ is...

1.1.1. Definitions 1. Bounded Above (for a set): Let S ⊂ R. S is bounded above if ∃L ∈ R such that x ≤ L for all x ∈ S. L is called an upper bound for S. (Similar definition for bounded below and lower bound) 2. Bounded (for a set): Let S be a set. S is bounded if S is bounded above and bounded below. 3. Least Upper Bound (LUB) Axiom for R (for a set): Let S ⊂ R be bounded above. Then !∃L ∈ R s...

In this paper X denotes a set. Let L be a lattice. Note that Poset(L) has l.u.b.’s and g.l.b.’s. Let L be an upper-bounded lattice. One can verify that Poset(L) is upper-bounded. Let L be a lower-bounded lattice. One can verify that Poset(L) is lower-bounded. Let L be a complete lattice. Note that Poset(L) is complete. Let X be a set. Then X is an order in X . Let X be a set. The functor 〈X ,⊆〉...

This paper investigates geometric stability and L p-stability of discrete-time Markov chains associated with closed and open queueing networks with Markovian routing. By geometric stability (resp. L p-stability) we mean that the chain is re-generative in the Harris-recurrent sense and that the times between the successive regeneration points have a bounded moment generating function (resp. a bo...

Let $X$ be a Banach space of $dim X > 2$ and $B(X)$ be the space of bounded linear operators on X. If $L : B(X)to B(X)$ be a Lie higher derivation on $B(X)$, then there exists an additive higher derivation $D$ and a linear map $tau : B(X)to FI$ vanishing at commutators $[A, B]$ for all $A, Bin B(X)$ such that $L = D + tau$.

It is shown that the aliasing probability is bounded above by (1 + E ) / L M 1/L ( E small for large L) for test lengths L less than the period, L,, of the signature polynomial; for test lengths L that are multiples of L,, the aliasing probability is bounded above by 1; and, for test lengths L greater than L, and not a multiple of L,, the aliasing probability is bounded above by 2 / ( L c + 1)....
