[Seminar] Sub-Gaussian heat kernel bounds and singularity of energy measures for symmetric diffusions,Professor Naotaka Kajino (Kyoto University)
This talk will present the result of a joint work with Mathav Murugan(University of British Columbia) that, for a symmetric diffusion on a complete locally compact separable metric space, two-sided sub-Gaussian heat kernel bounds imply the singularity of the energy measures with respect to the reference measure.
For self-similar (scale-invariant) diffusions on self-similar fractals, the singularity of the energy measures is known to hold in many cases by Kusuoka (1989, 1993), Ben-Bassat, Strichartz and Teplyaev (1999), Hino (2005), and Hino and Nakahara (2006), but these results heavily relied on the self-similarity of the space.
It was conjectured, and had remained open for the last two decades to prove, that the singularity of the energy measures should follow, without assuming the self-similarity, just from two-sided sub-Gaussian heat kernel bounds of the same form as those for diffusions on typical self-similar fractals. The main result of this talk answers this conjecture affirmatively.
The first half of the talk will be devoted to a brief introduction to self-similar diffusions (and their associated Dirichlet forms) on self-similar fractals and to sub-Gaussian heat kernel bounds for symmetric diffusions, so that the talk will (hopefully) be accessible even to those without prior knowledge about diffusions on fractals.

Title: Individual-based temporal beta-diversity: Individual turnover and compositional shift in a community
Timeline 15:00~15:30: seminar 15:30~16:00: questions and discussion 16:00~: mixer
Abstract: As increasing the necessity to assess the influences of global climate change and anthropogenic disturbances on biodiversity, the concept of beta-diversity has been extended to a temporal context and has been intensively studied in recent years. In studies of temporal beta-diversity, methodologies used in spatial beta-diversity have often been used simply. However, temporal beta-diversity often includes "the same individual" between two communities implicitly, which has not been the case with spatial communities, so it is necessary to consider the effects of individual turnover and persistence for quantifying temporal beta-diversity. I focused on both individual identity and the persistence of individuals within a temporal beta-diversity framework and developed some novel indices. In my presentation, I will explain the novel indices which I recently developed and the concepts behind them, showing examples of analysis. I would also like to discuss the prospects for community assemblages through both time and individual identity.

[Seminars] Macroscopic Quantum Machines
These seminars examine the science of how to bring macroscopic (large) systems into the quantum regime. The preparation of large Schrodinger cats is one of the long sought goals of quantum science. Researchers seek to do this for many reasons – to see if it can be done at all – does quantum mechanics still hold for large objects – is there new science that appears when objects become large/massive? Can macroscopic/large quantum systems be useful as precision sensors – and how can we preserve/protect the large scale quantum properties in such systems. These series of talks (experimental and theoretical), will show some facets/aspects of how some researchers are aiming towards the building of large Quantum Cats. Coffee and Okinawan Donuts are supplied during the morning.

Lunchtime Seminar (Dr. Yuimaru Kubo, STG)
Title: A masing spin ensemble: temperature, light, amplifier, and diamond
Abstract:
I will start discussing two fundamental concepts in nature, temperature and light, followed by one of the indispensable basic components in the modern information society, amplifiers. Then I will try to show that combining these three concepts leads to our ongoing project, a heat-driven coherent microwave oscillator based on a spin ensemble in a diamond crystal.

[Seminar] Supercaloric functions for the parabolic p-Laplace equation in the fast diffusion case, Juha Kinnunen, Aalto University
This talk discusses a generalized class of supersolutions, so-called \(p\)-supercaloric functions, to the parabolic \(p\)-Laplace equation. This class of functions is defined as lower semicontinuous functions that are finite in a dense set and satisfy the parabolic comparison principle. Their properties are relatively well understood in the slow diffusion case \(p>2\), but little is known in the fast diffusion case \(1
[Mini-course] Curvature and Optimal transport | Professor Asuka Takatsu, Tokyo Metropolitan University
In this series of lectures, I first review the notion of curvature (Gaussian curvature and Ricci curvature). In particular, I recall some comparison theorems (Toponogov's triangle comparison theorem, Bishop--Gromov volume comparison theorem etc). Then I introduce a generalized notion of curvature in non-smooth spaces.
