Capelli's identity

In mathematics, Capelli's identity, named after Alfredo Capelli, is an analogue of the formula det(AB) = det(A) det(B), for certain matrices with noncommuting entries, related to the representation theory of the Lie algebra . It can be used to relate an invariant ƒ to the invariant Ωƒ, where Ω is Cayley's Ω process. (Wikipedia).

Catalan's Identity for Fibonacci Numbers

We prove Catalan's identity involving Fibonacci numbers using an interesting property of matrices known as the determinant sum property. This is similar to two other identities which we proved in the following videos: Cassini's Identity: https://youtu.be/pn0J0p0R_GM d'Ocagne's Identity: h

Dimitry Gurevich - q-cut-and-join Operators and q-Capelli Identity on Reflection Equation Algebras

There exists a way, based on the notion of Quantum Doubles, to introduce analogs of partial derivatives on the so-called Reflection Equation algebras. Analogously to the classical case it is possible to use these ”q-derivatives” for different applications. I plan to explain their utility f

The Mafia: Fact and Fiction

For millions of people, the word 'mafia' conjures images of "The Godfather" and "The Sopranos". But what is 'the Mafia', exactly? Where does the term come from, and how has the definition changed over time? SUBSCRIBE | http://bit.ly/stdwytk-sub WEBSITE | http://bit.ly/stdwytk-home AUD

The Millin Series (A nice Fibonacci sum)

We derive the closed form for the Millin series, which involves reciprocals of the 2^nth Fibonacci numbers. We use Catalan's identity, the convergence of a subsequence, and the golden ratio. Catalan's Identity: https://youtu.be/kskAtiWC_w8 Another reciprocal Fibonacci sum: https://youtu.b

The golden ratio | Lecture 3 | Fibonacci Numbers and the Golden Ratio

The classical definition of the golden ratio. Two positive numbers are said to be in the golden ratio if the ratio between the larger number and the smaller number is the same as the ratio between their sum and the larger number. Phi=(1+sqrt(5))/2 approx 1.618. Join me on Coursera: http

Beltrami Identity Derivation

The Beltrami Identity is a necessary condition for the Euler-Lagrange equation (so if it solves the E-L equation, it solves the Beltrami identity). Here it is derived from the total derivative of the integrand (e.g. Lagrangian).

Vera Serganova: Capelli eigenvalue problem for Lie superalgebras and supersymetric polynominals

Abstract: We study invariant differential operators on representations of supergroups associated with simple Jordan superalgebras, in the classical case this problem goes back to Kostant. Eigenvalues of Capelli differential operators give interesting families of polynomials such as super J

Dimitry Gurevich - New applications of the Reflection Equation Algebras

The REA are treated to be q-analogs of the enveloping algebras U(gl(N)). In particular, each of them has a representation category similar to that of U(gl(N)). I plan to exhibit new applications of these algebras: 1. q-analog of Schur-Weyl duality 2. q-Capelli formula 3. q-Frobenius formul
