WebbDetails about plethysm. I'm currently working on plethysm, i.e. the character of the composition S λ ( S μ ( V)) of the Schur functors S λ and S μ on a complex vector space V. We note this character s λ [ s μ]. One must know that the character of S μ ( V) is the Schur function s μ. We want to find the irreductible representation of S λ ... In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x. For example, since 1000 = 10 , the logarithm base 10 of 1000 is 3, or log10 (1000) = 3. The logarithm of x to base b is denoted as logb (x), or without parentheses, logb x, or even without the explicit base, log x, whe…
Webb15 sep. 2024 · These are lecture notes for a mini-course at the SCGP in March 2024 for the fourth workshop on the Geometry and Physics of Higgs bundles. In this course, we explore similarities between moduli of quiver representations and moduli of vector bundles over a smooth projective curve. After describing the basic properties of these moduli problems … Webb21 jan. 2024 · We study intersection cohomology of character varieties for punctured Riemann surfaces with prescribed monodromies around the punctures. Relying on previous result from Mellit [Mel17b] for semisimple monodromies we compute the intersection cohomology of character varieties with monodromies of any Jordan type. This proves …
Webb3 feb. 2024 · We express our formula as a generating function identity involving the plethystic logarithm of a product of sums over Young diagrams. The Pieri’s formula for multiplying Schur polynomials arises in an interesting way. This is … WebbThe plethystic notation is a very flexible way of handling different sets of variables to evaluate. To specify an algebra homomorphism from Λ it suffices to specify it on each p n Consider a Laurent series A in some indeterminates a 1, a 2, a 3 ⋯ Given a symmetric function f the plethystic substitution f [ A] is the image of f under the ...
WebbIn algebra, plethysm is an operation on symmetric functions introduced by Dudley E. Littlewood, [1] who denoted it by { λ } ⊗ { μ }. The word "plethysm" for this operation …
WebbSimplification and evaluation of logarithms is governed by several global flags: logexpand causes log(a^b)to become b*log(a). set to all, log(a*b)will also simplify to log(a)+log(b). If it is set to super, then log(a/b)will also simplify to (log(1/b), for binteger, always simplifies.) false, all of these simplifications will be turned off. logsimp quarter round wire channelWebb15 feb. 2024 · The rest of this article is arranged as follows: in Sect. 2, we introduce the basic notations for partitions, symmetric functions, and plethystic operators.Then, we … shipman canterbury talesWebb1 maj 2015 · The algebraic structure of the Coulomb branch of the 3d mirrors of A s, p models is captured by the plethystic logarithm of the Hilbert series of [10].
