Title : Korevaar-Schoen-Sobolev spaces and critical exponents on metric measure spaces Speaker: Fabrice Baudoin , University of Connecticut Abstract: We will review some of the recent developments in the theory of Korevaar-Schoen-Sobolev spaces. While this theory is equivalent to that of Cheeger and Shanmugalingam if the space supports a Poincare inequality, it offers new perspectives in situations, like fractals, where such inequalities are not available.

Title: Convexity in Partial Differential Equations

Abstract: It is well known that the notion of convexity plays a key role in optimization, control theory, mathematical economics and many other areas of science. This talk is a friendly introduction to convex analysis for partial differential equations. After going over a few basic properties about convex sets and convex functions, we will focus on the preservation of spatial convexity of solutions, which is one of the most important geometric properties of numerous evolution equations. Several examples will be given. We will also discuss some recent developments on this topic.

This talk is open to everyone at OIST

Title: Cantor Julia sets

Speaker : Vyron Vellis,University of Tennessee

Abstract: The Julia set of a meromorphic function is the set of “chaotic points”, i.e., the set of all points that have no neighborhood under which the iterates of the function form a normal family. In absence of a rich holomorphic function theory in higher dimensions, the right substitute in complex dynamics are uniformly quasiregular (UQR) maps. Which Cantor sets can appear as Julia sets of UQR maps? How (topologically) complex can such sets be? This talk is based on joint works with Alastair Fletcher and Daniel Stoertz.

Neural mechanisms for memory and emotional processing during sleep

The hippocampus and the amygdala are two structures required for emotional memory. While the hippocampus encodes the contextual part of the memory, the amygdala processes its emotional valence. During Non-REM sleep, the hippocampus displays high frequency oscillations called “ripples”. Our early work shows that the suppression of ripples during sleep impairs performance on a spatial task, underlying their crucial role in memory consolidation. We more recently showed that the joint amygdala-hippocampus activity linked to aversive learning is reinstated during the following Non-REM sleep epochs, specifically during ripples. This mechanism potentially sustains the consolidation of aversive associative memories during Non REM sleep. On the other hand, REM sleep is associated with regular 8 Hz theta oscillations, and is believed to play a role in the regulation of emotional reactions and the consolidation of emotional memories (emotional processing). Unraveling the fine neuronal dynamics related to REM sleep, Non-REM sleep and the transitions between states in the hippocampus-amygdala network will further our understanding of the implication of these sleep stages and related brain patterns in emotional processing.

Title: Inference, control and the cortical circuits

Abstract:

The duality of sensory inference and motor control has recently been recognized as the commonality in computations required for the posterior distributions in Bayesian inference and the value functions in optimal control. Meanwhile, an intriguing question about the brain is why the entire neocortex shares a canonical six-layer architecture, while its posterior and anterior halves are engaged in sensory processing and motor control, respectively. Here we consider the hypothesis that the sensory and motor cortical circuits implement the dual computations for Bayesian inference and optimal control,

Title: Are black holes and particles the same thing?

Abstract: I'll discuss the similarities between fundamental particles, thermal systems and black holes. We will play some quantitative games to see exactly how black holes are different from particles in the real world.

Having paid the real world our respects, we will talk about how black holes and fundamental particles *are* the same in string theory - a story rarely covered in popular propaganda, but central to the second superstring revolution. Funny enough, it allows for the "discovery" of new particles through writing down new black hole solutions.

I will then advertise my current work, in which I'm doing exactly that for string theory's wonky cousin, Higher-Spin Gravity.
