Essa descrição será feita de dois modos distintos: através de produtos modulares concatenados, mostrando que uma tal linguagem pertence à álgebra de Boole gerada por produtos modulares concatenados de linguagens comutativas elementares e, através de transdutores, provando que essas linguagens são combinações Booleanas de linguagens da forma rτ−1, em que p é um número primo, r ∈ Zp e τ : A∗ → Zp é uma função realizada por algum transdutor na forma triangular estrita.Com vista a esse estudo, faremos uma análise detalhada da pseudovariedade dos grupos super-resolúveis e também de outras pseudovariedades de grupos, em particular, das pseudovariedades dos p-grupos e dos grupos abelianos cujo expoente divide um dado natural n. Caracterizaremos também o produto de pseudo variedades e daremos especial atenção à pseudovariedade Gp ∗ Abp−1. Estudaremos as variedades de linguagens associadas às pseudovariedades de grupos consideradas e iremos demonstrar o Princípio do Produto em Coroa de Straubing, o qual nos fornece uma descrição das linguagens reconhecidas pelo produto em coroa de dois monóides. Além disso, apresentaremos uma versão deste princípio para variedades de linguagens. Será ainda considerado o produto de linguagens com contador e descrita a operação entre monóides que lhe está associada.</dcterms:abstract><dc:subject>Matemática</dc:subject><dc:language>por</dc:language><dcterms:accessRights>open access</dcterms:accessRights><dc:type>info:eu-repo/semantics/masterThesis</dc:type><dc:format>application/pdf</dc:format><dc:link>http://catalogo.ul.pt/F/?func=item-global&amp;doc_library=ULB01&amp;type=03&amp;doc_number=000561442</dc:link><dcterms:abstract>The main subject of this work is to give a description of the languages recognized by finite super-soluble groups. That description will be done in two distinct ways. The first one uses the modular concatenation product, more precisely, we will prove that such a language is in the Boolean algebra generated by the concatenated modular products of elementary commutative languages. In the second one we prove that the languages recognized by super-soluble groups are Boolean combinations of languages that take the form of rτ−1, where p is a prime number, r ∈ Zp and τ : A∗ → Zp is a function realized by some transductor in the strict triangular form. In view of that study, we will analyse in detail the pseudovarieties of super-soluble groups as well as other pseudovarieties of groups, in particular we will consider the pseudovariety of p-groups and the pseudovariety of abelian groups whose exponent divides a given natural n. We will also characterize the product of pseudovarieties, dedicating particular attention to the pseudovariety  Gp ∗ Abp−1.We will study the varieties of languages associated with the pseudovarieties of groups considered and will prove the Straubing`s Wreath Product Principle, which gives us a description of the languages recognized by the wreath product of two monoids. In addition, we will present a version of this principle applied to varieties of languages. The product of languages with counter will also be considered and the associated operation between monoids will be described.</dcterms:abstract><dc:subject>Teses de mestrado</dc:subject></record>]]></value></md></mds><relations/><stream_ref><file_name>19926_ulfc091534_tm_TeseEliana.pdf</file_name><file_extension>pdf</file_extension><mime_type>application/pdf</mime_type><directory_path>/digitool_storage/deposit-master/2009/11/06/file_1/19926</directory_path><file_id xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/><storage_id>1006</storage_id><external_type>-1</external_type><file_size_bytes>999366</file_size_bytes></stream_ref></xb:digital_entity></xb:digital_entity_call>
