University of Isfahan and IPM-Isfahan Workshop and Seminar on Linkage TheoryISFAHAN BRANCH OF MATHEMATICS January 17-18, 2018 IPM-Isfahan ... 14:00 - 15:30 Weekly SeminarPrimordial anisotropies from defects during inflation School ASTRONOMY In this talk we review the imprints of various defects present during inflation on primordial power spectrum. In particular, we look at the effects of a domain wall, a cosmic string, a massive monopole and the vacuum bubble during inflation. We show that these defects generate non-trivial scale-dependent power anisotropies which can be tested from CMB observations ... 15:30 - 17:00 Geometry and Topology Weekly SeminarSkew Products and Invariant Graphs School MATHEMATICS This talk concerns the stability and ergodic properties of skew products $T(x, y) =(f(x), g(x, y))$ in which $(f, X, mu)$ is an ergodic map of compact metric space $X$ and $g : X imes Y ightarrow Y$ is continuous. The set $X$ is the base, while $Y$ is the fiber. We consider the case where g is (non-uniformly) contracting. When this contraction is uniform, it can easily be shown that there exists a globally attracting invariant set which is the graph of a function from the base space to the fiber space. Here, we consider the case that the contraction rates are non-uniform and hence specified by Lyapunov exponents and analogous quantities. ... 15:30 - 16:30 Weekly SeminarProbabilistic Theories of Critical Phenomena, and the Dimer Model School PARTICLES AND ACCELERATORS The probabilistic theories of critical phenomena have been undergoing intense development during the last two decades. Drawing on ideas from statistical physics, many 2D critical lattice models are conjectured or even proved to have conformally invariant scaling limits. We begin by reviewing some fundamental random objects including curves, loop ensembles and surfaces, which arise universally and canonically in these systems, and explain how they are related to many contexts in physics. We then introduce the planar (double-)dimer model as a statistical mechanical model of random 2-dimentional interfaces, and present some results which support ... 16:00 - 18:00 Neuroimaging Journal ClubCanonical Correlation Analysis for Data Fusion and Group Inferences School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran ... 17:00 - 18:00 Ph.D. Defense SessionThe Hermitian Yang-Mills Connections on $mathbb{C}^n$ and Asymptotic Stability on $mathbb{CP}^n$ School MATHEMATICS ... |
