The two Working Days on Orthogonal Polynomials, Special Functions, Integral Transforms and Applications are organized by the Analysis Area of the Centro de Matemática da Universidade do Porto (CMUP) and will be held at Departamento de Matemática Aplicada (DMA) of Faculdade de Ciências da Universidade do Porto (FCUP). This event takes place following the past two meetings held in 2003 and 2006, that gathered PhD students and supervisors working in the field of orthogonal polynomials, padé-approximants and linear systems. The main goal of these meetings was to produce a balance of the on-going research. This year, the scope of the event was broaden to other strongly related fields, such as special functions and integral transforms bringing particular focus to their applications in science. Hence, it aims to stimulate a higher interaction between the debated fields and to generate a consequent enrichment of the PhD students and researchers work. The meeting also has the parallel purpose of raising the awareness of students and researchers who have not worked specifically on the referred subjects, but who currently might intend to develop studies on them. The lectures will be given by researchers and PhD students, whose work deals with orthogonal polynomials, special functions, integral transforms, problems in approximation theory, padé-approximants and applications. Each lecture will take about 20 minutes followed by a 10 minute discussion. Main topics: - orthogonal polynomials - special functions - integral transforms - problems in approximation theory - padé-approximants - applications in science.
