Abstract: Preliminary Course Outline:
(1) Elementary introduction to arc spaces and their relations with vertex algebras
(2) Associated varieties of vertex algebras and representation theory of affine vertex algebras
(3) Introduction to BRST reduction and W-algebras
(4) Representation theory of W-algebras and (Frenkel)-Kac-Wakimoto conjecture
Victor Kac: Introduction to vertex algebras, Poisson vertex algebras, and integrable Hamiltonian PDE

(3) Variational de Rham complex
(4) Classical Hamiltonian reduction and classical W-algebras

Fyodor Malikov: Introduction to algebras of chiral differential operators
Abstract:
(1) Elementary introduction to usual algebras of differential operators. We shall focus on the example of the projective line and see how this theory relates to the representation theory of sl(2).
(2) Algebras of chiral differential operators on the projective line and their relations to the affine sl(2).
(3) Higher dimensional generalization: characteristic classes, flag manifolds, and affine Kac-Moody algebras.
Every effort will be made to make this course accessible and self-contained.
Seminar
Drazen, Adamovic C2 cofinite vertex algebras and representations of affine vertex algebras Abstract: We shall first recall the representation theory certain C2 cofinite vertex algebras appearing in logarithmic conformal field theory (joint work with A. Milas). We shall discuss classification of irreducible modules, the structure of Zhu’s algebras and the construction of projective modules. We shall show that the representation theory of certain affine vertex algebras are related with these vertex algebras. New explicit realizations of modules for affine Lie algebras and superconformal algebras will be also presented.
Sylvain Carpentier TBA
Masahiko Miyamoto Vertex Operator Algebra and Simultaneous Inversion
Abstract: Let V be a C2-cofinite vertex operator algebra. We define a multivariable trace functions on V -modules and show a modular invariance property. We would like to introduce a few applications of this result.
Pierluigi Mosender Finite vs infinite decompositions in conformal embeddings
Abstract:The talk will be a report on a work in progress aimed at the classification of conformal embeddings of affine vertex algebras exhibiting finite decompostion properties.
Anne Moreau The symmetric invariants of centralizers and Slodowy grading
Abstract: Let g be a complex finite-dimensional simple Lie algebra, and let e be a nilpotent element of g. An interesting question, raised by Premet, is whether the algebra of symmetric invariants of the centralizer of e is polynomial. In 2007, Premet, Panyushev and Yakimova resolved the question in some special cases; in particular, the answer is positive for g of type A or C.
In this talk, I will present a joint work with Jean-Yves Charbonnel in which we continue the works of Premet et al. Our main result says that if for some homogeneous generators of S(g)g, the initial homogeneous components of their restrictions the to Slodowy slice of e are algebraically independent, then e satisfies the polynomiality condition. The key to the proof is the use of the Slowody grading induced from the finite W-algebra associated with (g, e).
Daniele Valeri Classical W-algebras and generalized Drinfeld-Sokolov hierarchies
Abstract: I will describe the Poisson vertex algebra approach to classical W-algebras aimed at the study of integrability of the corresponding generalized Drinfeld-Sokolov hierarchies.
Jethro van Ekeren Jacobi Invariance of SUSY Vertex Algebras
Abstract: We explain how to construct conformal blocks over superelliptic curves associated to topo- logically twisted N=2 SUSY vertex algebras. The geometry of the moduli space of such supercurves leads to a natural action of the Jacobi group SL(2, Z) × Z2 which, in the presence of some regularity conditions on the vertex algebra, implies Jacobi invariance of its characters.

Introduction to Socrates

# You can also click the upper-left icon to select videos from the playlist.

source: Academy of Ideas 2013年3月23日
In the first lecture of this 3 part series we look at the Socratic problem, which is the problem as to whether we can arrive at knowledge of the historical Socrates. In the final two lectures we examine the life and ideas of Socrates.

Socrates: The Socratic Problem 10:28 In this lecture we investigate what is known as the Socratic problem, which is the problem as to whether we can arrive at knowledge of the historical Socrates, or whether he will always remain nothing but a work of fiction. We also look at the Socrates of Plato's dialogues, and consider the question as to whether Plato was using Socrates as a mouthpiece for his own views, or espousing the actual ideas of the real Socrates.
Socrates: The Man and His Life 8:34 In this lecture we investigate the life of Socrates. In particular, we look at two monumental events in his life: his encounter with the oracle at Delphi which pronounced him to be the wisest of all men, and his trial and subsequent execution.
The Ideas of Socrates 10:56 In this lecture we examine the ideas of Socrates. We look at his exhortation to 'care for your soul', his conviction that knowledge of virtue is necessary to become virtuous, his belief that all evil acts are committed out of ignorance and hence involuntarily, and finally his presumption that committing an injustice is far worse than suffering an injustice.

The Presocratics

Introduction to the Presocratics 12:58 In this lecture we introduce the Presocratics, discover why they deserve our attention, and investigate the difference between mythology and philosophy.

Introduction to Kierkegaard

In this 2 part series, we introduce to ideas of the 19th century Danish philosopher Soren Kierkegaard, considered by many to be the "father of existentialism".

Introduction to Kierkegaard: The Existential Problem 14:15
In this 1st of 2 videos introducing Kierkegaard, we summarize some of his ideas (freedom, anxiety, dread, despair, subjective truth) that led to his title as the "father of existentialism".
Introduction to Kierkegaard: The Religious Solution 16:22
In this video we summarize Kierkegaard's 3 life-views, the aesthetic, the ethical, and the religious, and their appropriateness for the eradication of despair. We investigate his ideas on faith, and portray the individual he called the "knight of faith".
