  6. 9. On the linearization of non-Archimedean holomorphic functions near an indifferent fixed point

    Author : Karl-Olof Lindahl; Andrei Khrennikov; Franco Vivaldi; Växjö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynamical system; linearization; conjugation; non-Archimedean field; Algebra; geometry and mathematical analysis; Algebra; geometri och analys; Mathematics; Matematik;

    Abstract : We consider the problem of local linearization of power series defined over complete valued fields. The complex field case has been studied since the end of the nineteenth century, and renders a delicate number theoretical problem of small divisors related to diophantine approximation. READ MORE

  7. 10. Path Integral studies of quantum systems at finite temperatures

    Author : Sergei Ivanov; Alexander Lyubartsev; Ben Leimkuhler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; path integral; molecular dynamics; algorithms; quantum simulations; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis presents and develops the path integral simulation techniques in application to small quantum systems at finite temperatures. The first goal is to obtain exact thermodynamic expressions for systems of noninteractingThe rest and the major part of the thesis is dedicated to the development and testing of Bead-Fourier path integral molecular dynamics.
