Several of the contributions to this quantity carry ahead many at the same time necessary interactions and connections among the 3 domain names of the identify. constructing them was once the most objective of the NATO ASI summerschool held in Montreal in 2003. even supposing a few connections, for instance among semigroups and automata, have been recognized for a very long time, constructing them and surveying them in a single quantity is novel and confidently stimulating for the longer term. one other point is the emphasis at the structural conception of automata that reviews how you can contstruct monstrous automata from small ones. the amount additionally has contributions on best present examine or surveys within the 3 domain names. One contribution even hyperlinks clones of common algebra with the computational complexity of laptop technological know-how. 3 contributions introduce the reader to analyze within the former East block.

5 there exists a continuous homomorphism ϕ : Ωm V → S such that S ∈ V and K = ϕ−1 ϕK. Let W = V(S). Then ϕ factors through the natural projection πm : Ωm V → Ωm W and so we may as well assume that S = Ωm W. Consider the following diagram where πn : Ωn V → Ωn W is also a natural projection and the horizontal arrows represent composition of implicit operations deﬁned for each of the pseudovarieties V and W as above: The commutativity of the diagram follows from the fact that implicit operations commute with continuous homomorphisms between pro-V semigroups: πm (v(w1 , .

Sn ∈ K such that n K⊆ Bδ (si ). 3) i=1 Let f ∈ V (K, U ) ∩ End S and let n V ({si }, Bδ (f (si ))) ∩ End S. W = i=1 Then W is an open set of End S in the pointwise convergence topology which contains f . Hence it suﬃces to show that W ⊆ V (K, U ). Let g ∈ W and s ∈ K. 3), there exists i ∈ {1, . . , n} such that d(s, si ) < δ. 11, we have d(g(s), g(si )) < δ. On the other hand, since g ∈ V ({si }, Bδ (f (si ))), we obtain d(g(si ), f (si )) < δ. Since d is an ultrametric, it follows that d(g(s), f (si )) < δ.

Wn ) and the vi and wi are κ-terms such that Gp |= vi = wi and the determinant of the matrix (|wi |xj )i,j is invertible in Z/pZ. Here for a κ-term w and a letter x, |w|x is the integer obtained by viewing w as a group word and counting the signed number of occurrences of x in w. So, for example, if ϕ is given by the pair ((xy)ω−1 yxω , x3 yxω−1 ) 0 then we get det −1 2 1 = −1. We do not know if Gp is completely tame with respect to this signature. 32 7 J. Almeida Categories, semigroupoids and semidirect products Tilson [90] introduced pseudovarieties of categories as the foundations of an approach to the calculation of semidirect products of pseudovarieties of semigroups which had emerged earlier from work of Knast [50], Straubing [86], and Th´ erien and Weiss [88, 92].
