"Mixed joint universality for Dirichlet L-functions and Hurwitz type zeta-functions" /"Dirichlė L funkcijų ir Hurvico tipo dzeta funkcijų mišrus jungtinis universalumas".Janulis, Kęstutis,info:eu-repo/semantics/openAccessMized joint universality ; Dirichlet L-functions ; Hurwitz type zeta-functionsThe aims of the thesis are mixed joint universality theorems for Dirichlet L-functions and Hurwitz type zeta-functions, i.e., theorems on simultaneous approximation of a collection of analytic functions by shifts of Dirichlet L-functions which have Euler's product over primes and by shifts of Hurwitz type zeta-functions which have no the Euler product. The problems are the following: 1. A mixed joint universality theorem for Dirichlet L-functions and Hurwitz zeta-functions; 2. A mixed joint universality theorem of Dirichlet L-functions and periodic Hurwitz zeta-functions; 3. The universality of composite functions of a collection of Dirichlet L-functions and Hurwitz zeta-functions; 4. The universality of composite functions of a collection of Dirichlet L-functions and periodic Hurwitz zeta-functions.Institutional Repository of Vilnius UniversityLaurinčikas, Antanasinfo:eu-repo/semantics/doctoralThesiseng2015application/pdfhttps://epublications.vu.lt/object/elaba:13947495/13947495.pdfhttps://repository.vu.lt/VU:ELABAETD13947495&prefLang=en_US
