| 10:00 - 12:00 Lecture Non-Classical Logic: An Overview School PHILOSOPHY Non-Classical Logic: An Overview ... 13:30 - 15:00 Weekly Seminar AGB populations as probes of galaxy formation and evolution School ASTRONOMY The evolution of galaxies is driven by the birth and death of stars. Asymptotic Giant Branch (AGB) stars are at the end points of their evolution and therefore their luminosities directly reflect their birth mass; this enables us to reconstruct the star formation history (SFH). These cool stars also produce dust grains that play an important role in the temperature regulation of the interstellar medium, chemistry, and the formation of planets. These stars can be resolved in all of the nearby galaxies. Therefore, the Local Group of galaxies offers us a superb near-field cosmology site. Here we can reconstruct the formation histories, and probe ... 14:00 - 15:30 Combinatorics and Computing Weekly Seminar Eigenvalues and Structures of Weighted Graphs School MATHEMATICS Let S(G) be the set of all real symmetric matrices such that their offdiagonal entries are nonzero if and only if the corresponding vertices in the graph G are connected by an edge. The diagonal entries can be both zero and nonzero. In this talk, we will focus on the eigenvalues of these matrices. In particular, we are interested in q(G), the minimum number of distinct eigenvalues of a matrix in S(G). We will survey some results about the parameter q(G). ... 14:00 - 16:00 Seminar Cognitive Musicology, Part I School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran on map * To join the mailing list: Send an empty email to: scs at ipm dot ir on the subject of: #join ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Superhydrophobicity in copper based layers School PHYSICS Seminar Room (classroom A), Farmanieh Building, IPM ... 14:00 - 15:00 Weekly Seminar Superhydrophobicity in copper based layers School NANO SCIENCES Superhydrophobicity in copper based layers Abstract: One of the relevant approaches to keep surfaces clean without a secondary process is to use the easy-to-clean and superhydrophobic surfaces technology. These superhydrophobic surfaces have a wide potential applications in the environment and industries. When the hydrophobicity is mixed with catalytic properties of copper oxide, a more useful surface for electrical and environmental applications is obtained. According to the recent researches, the preparation of one-step durable superhydrophobic surface whiteout a secondary chemical or physical modificatio ... 15:00 - 16:00 Weekly Seminar Hamiltonian structure of Multi-Gravity models School PARTICLES AND ACCELERATORS Abstract: In this talk, I will shortly review the recent results in Hamiltonian structure of Massive Gravity and HR Bi-Gravity in nonlinear level. Then, I will specifically focus on the Hamiltonian structure of three and four gravity. Finally, I present a perfect Hamiltonian structure for a multi-gravity model in the full phase space. Larak Seminar Room 16:00 - 17:00 Mathematics Colloquium Metastability and Condensation (canceled) School MATHEMATICS Dynamical systems that are perturbed by small random noises are known to exhibit metastable behavior. Analogously, random walks with tendency towards a finite collection of sites may exhibit metastability. Zero Range Process is a random walk on a simplex with metastable states residing at the vertices. Interpreting this process as a particle system on a one dimensional lattice, the metastable states correspond to the condensates. In this talk I give an overview of some known results in both the continuous and discrete settings, and discuss some open questions. ... |
