The talk will provide an overview of the research that has been done on this topic, nearly all of which has focused on settings in which the reselling channel sells only the product of the encroaching manufacturer. It will also include new results for a setting in which the reseller has the ability to sell the product of another manufacturer. It turns out that this outside option for the reseller can dramatically alter the interactions between a manufacturer and the reseller. For instance, the reseller's benefit from the development of a direct channel disappears when the product substitutability exceeds a threshold. In addition, we find that the non-encroaching manufacturer can benefit from her rival's direct channel.  Finally, we find that even when the encroaching manufacturer’s direct channel is more efficient than the reseller’s channel, the encroaching manufacturer will nevertheless continue to sell through the reseller when there is a highly substitutable product available.

Venue: Lecture Hall, 4th floor, Sir Run Run Shaw Business Administration Building, Yuquan CampusSpeaker: David Saintillan, Professor of Mechanical and Aerospace Engineering, University of California, San DiegoAbstract:The spontaneous emergence of large-scale coherent motions and patterns is a striking feature of many active soft matter systems and often results from long-ranged hydrodynamic interactions driven by internal active forces. In the first part of my talk, I will focus on bacterial suspensions, where hydrodynamic instabilities are known to arise due to the force dipoles exerted by motile microorganisms which couple to their orientations through the flows they generate. Using both continuum modeling and numerical simulations, I will analyze the interplay between these instabilities and geometrical confinement, where an apparent transition to superfluidity can be harnessed to drive unidirectional streaming flows. The second part of the talk will address the seemingly very different – yet perhaps related – case of chromosomal dynamics inside the nucleus during cell interphase, where experiments recently revealed coherent motion on large length and time scales. A model of chromatin dynamics as a confined polymer chain acted upon by molecular enzymes exerting force dipoles will be discussed, where hydrodynamic interactions emerge once again as a potential mechanism for coherent motions and large-scale self-organization.

Venue: Lecture Hall, 4th floor, Sir Run Run Shaw Business Administration BuildingSpeaker: Irene M. Gamba, Professor in Mathematics, W.A. Tex Moncreif, Jr. Chair in Computational Engineering and Sciences III. Leader for the ICES Applied Mathematics Group, the University of Texas at AustinAbstract:We look into the Cauchy problem for Homogeneous Boltzmann problems without initial bounded entropy and solve by means of theorem for ODE systems in Banach spaces. The technique works for collision frequencies satisfy that the larger the relative momentum the higher rate of interactions (i.e. hard potential) types with integrable angular cross section, and initial data the allows for a lower bound on the total collision frequency.This functional analysis, initially proposed for the Boltzmann equation, provides for a good tool works for a large variety of models, namely, the Cauchy problem  for the classical elastic Boltzmann monoatomic gas model for hard potential and integrable angular cross sections, as well as for the multi-component monatomic gas mixture model in a full non-linear binary interactions. In addition, we used it for the quantum Boltzmann equation for a system with a BEC condensation, and the wave turbulence model proposed by  Luov, Newell and Zacharov'95.
