New trends in conformal theory from probability to gravity, Okinawa, Japan --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=26670 Starting: 2023-07-31 to 2023-08-04 Location: Okinawa, Japan Additional Information: https://groups.oist.jp/cftprgr Contact: cftprgr[AT]oist.jp OIST workshop 2023 "New trends of conformal theory from probability to gravity". The study of conformal theory connects the theoretical physics and mathematics, which has been closely related to the representation theory of Lie group, algebraic geometry, topology and number theory. Recently the random matrix models have been discussed for quantum chaos of the black hole entropy, through a universal spectral form factor. This probabilistic study of the random matrix model and random tensor model may reveal the cases of the central charge c greater than one. The rational CFT for central charge c is less than one, are well known as minimal models and as Schramm-Loewner evolution in the probability theory. The gravity coupled to matter fields may be related to exotic random geometries. In this workshop, we focus a new relation between theoretical physics and mathematics: gravity and probability by new theoretical methods, such as conformal bootstrap methods and the studies of the eigenvalues of Calabi-Yau manifolds etc. Algebraic geometric structures like Thomson group and Moonshine will be also included for the study of complicated exotic geometries, which are related to CFT. The number theory related to p-adic group and modular form, and higher dimensional knots are topics of this workshop. Invited speakers are: Laurent Baulieu (LPTHE, Sorbonne Univ.)

MTW at 50 (online) ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=26604 Additional Information: The International Society on General Relativity and Gravitation (ISGRG) is organizing an online event to celebrate the 50th anniversary of the publication of Misner, Thorne and Wheeler's "Gravitation" (or "MTW"). The meeting (hopefully the first in a series - stay tuned!) will be on May 3 at 8:30am Pacific Time = 11:30am Eastern US Time = 5:30pm Central European Time via zoom at the following link: https://zoom.us/j/91275367125?pwd=Y2lFS1VoM0N2M1dOcGdvMzR2QkNZZz09 David Kaiser, who wrote the preface for the 2017 reprint of the book, will start off the meeting with an introduction. Both Charles Misner and Kip Thorne will participate. Kip will give a talk with the following title and abstract: *** The Creation, Life, Death and Resurrection of MTW: A 50 Year Retrospective In this talk I will describe - The historical context (a renaissance of relativity on the heels of a moribund era) in which Misner, Wheeler and I wrote Gravitation (MTW), and our motivations. - What each of us brought to our wonderful collaboration. - How we conceived, created and crafted this weird but wildly successful tome. - Our book's early reception and subsequent life. - Its death in a sequence of publisher acquisitions and its 2017 resurrection. To trigger discussion, I will offer my views on several issues: - MTW's unusually vivid and enthusiastic writing style, and the mixed reception it received from our eminent colleagues - e.g. S. Chandrasekhar's "It is written with the zeal of a missionary preaching to cannibals... but I (probably for historical reasons) have always been allergic to missionaries." - Its huge (for advanced physics texts of that era) ratio of words to equations. Why? - Our many "gimmicks" (in the word of one reviewer) and whether they "work": Two tracks, boxes that often extend over several pages, framed and unframed marginal notes, Part epigraphs, nearly a dozen fonts, .... - Our heavy emphasis on a geometric, as opposed to field-theoretic viewpoint, and Its contrast, for example, to Steven Weinberg's highly influential Gravitation and Cosmology. - MTW's appeal to nonscientists, such as the Berkeley street people of the Viet Nam War era. - MTW's influence on physics, astrophysics, and pedagogy over the decades. - What accounts for MTW selling 25,000 copies since its resurrection in 2017 (44 to 50 years after publication)? How useful for physicists is MTW today? *** The talk will be followed by a discussion / Q and A session. We hope you will join and celebrate this important milestone for our field.

Living Reviews in Relativity: "Searches for continuous-wave gravitational radiation" ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2023/04/19/living-reviews-in-relativity-... Additional Information: https://www.springer.com/journal/41114 The open-access journal Living Reviews in Relativity has published a new review article on 17 April 2023: Riles, Keith. Searches for continuous-wave gravitational radiation. Living Rev Relativ 26, 3 (2023). https://doi.org/10.1007/s41114-023-00044-3 Abstract: Now that detection of gravitational-wave signals from the coalescence of extra-galactic compact binary star mergers has become nearly routine, it is intriguing to consider other potential gravitational-wave signatures. Here we examine the prospects for discovery of continuous gravitational waves from fast-spinning neutron stars in our own galaxy and from more exotic sources. Potential continuous-wave sources are reviewed, search methodologies and results presented and prospects for imminent discovery discussed. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
