We show the connection between the method of adjoints in optimal control to the implicit function theorem ansatz. We relate the costate or adjoint state variable to Lagrange multipliers.

Algebraic properties of the adjoint. Null space and range of the adjoint. The matrix of T* is the conjugate transpose of the matrix of T.

Adjoint / Daggered Operators in Quantum Mechanics

In this video, we will explain adjoint operators in quantum mechanics. First of all, for any operator A, we can define its adjoint, A-dagger, via this equation. The idea behind this is, that while operators in quantum mechanics usually act towards the right, adjoint operators act to the le

ADVERBS OF DEGREE - ENGLISH GRAMMAR

Adverbs of degree are words that describe or modify adjectives or adverbs. They are a special type of adverb, so I don't really like to think of them as adverbs. They are best on their own category. These are also called intensifiers or qualifiers. If you want to support the channel, hit

Self-adjoint operators. All eigenvalues of a self-adjoint operator are real. On a complex vector space, if the inner product of Tv and v is real for every vector v, then T is self-adjoint.

What is an Injective Function? Definition and Explanation

An explanation to help understand what it means for a function to be injective, also known as one-to-one. The definition of an injection leads us to some important properties of injective functions! Subscribe to see more new math videos! Music: OcularNebula - The Lopez

In this video, I define the notion of adjugate matrix and use it to calculate A-1 using determinants. This is again beautiful in theory, but inefficient in examples. Adjugate matrix example: https://youtu.be/OFykHi0idnQ Check out my Determinants Playlist: https://www.youtube.com/playlist

Ch 9: What are Hermitian operators? | Maths of Quantum Mechanics

Hello! This is the ninth chapter in my series "Maths of Quantum Mechanics." In this episode, we'll take a look into what Hermitian operators are, and some of their properties. Then, we'll show how we can use our physical intuition to actually derive that physical observables must be Hermi

[Lesson 13] QED Prerequisites - The Pauli Spin Matrices...from scratch!

The purpose of this video is to motivate the Pauli Spin matrices from first principles. We will use these matrices a lot during the study of QED and it is critical that every aspect of their design and origin is well understood. This video begins by describing what it means to "rotate a sp
