Quantum Mechanics and the Transformation 1\(z-a)
Quantum Mechanics and the Transformation \( \frac{1}{z - a} \) Transformations of the form \( \frac{1}{z - a} \), especially in the context of complex analysis, appear in quantum mechanics,…
The Dirichlet problem and quantum entanglement
The Dirichlet problem and quantum entanglement are concepts from different branches of mathematics and physics, respectively, but there are indirect connections through the underlying mathematics. Dirichlet Problem The Dirichlet problem…
Contour Integration and Feynman Propagator
Contour integration is a powerful technique in complex analysis, used extensively in physics for evaluating integrals that arise in quantum field theory, especially when calculating Feynman propagators. Here's an explanation…
Exercises on Rings and Modules by T.Y. Lam
"Exercises on Rings and Modules" contains a collection of exercises designed to help students understand and practice concepts related to rings and modules in abstract algebra. Here are the key…
Examples of Hilbert Spaces
Hilbert Spaces can be FINITE dimensional or INFINITE Dimensional Finite Dimensional Hilbert Spaces n-Tuples of real numbers - $R^n$ - $R^5$ Inner Product would be just the dot product of…
Subspaces of Vector Spaces, Invariant Subspaces
The idea is to create a RESTRICTED space within the given vector space. Within R3 $\R^3$: $\{ \vec{i}, \vec{j}, \vec{k} \}$ we can define a space that is far more…
How to think of complex numbers
Think of it as a duo - there's actually TWO (real) numbers wrapped up in a single complex number. Think of it as a regular vector , but with a…
Vector Spaces Examples
The set of functions that take in a natural number n and return a REAL number. \ Functions of ONE Real Variable ( REAL to REAL) \ Of what use…
