Covariance of nonlinear sde

My problem is to compute the covariance of the following Ito process $$ dX_t=AX_t+\sum_{k=1}^{n}B_kX_tdW_k, $$ where $A,B_k$ are nonlinear operators defined on a complex separable Hilbert space $H$. ...

The intuition behind a matrix of a Hamiltonian?

We have derived an elegant partition function for a problem which resembles a quantized model taking the particles to be Bosons. The related Hamiltonian for every $i$th ensemble is there: $$H_i=\sum_{...

Spectrum of $H = - \Delta + y^2 + a e^{b(x+y)}$.

Define the Hamiltonian $$ H = - \Delta + y^2 + a e^{b(x+y)}\,, $$ where $- \Delta = - \partial_x^2 - \partial_y^2$ and $a,b > 0$. I'm trying to determine the spectrum and/or generalized ...

Computing Complex Ito calculus for stochastic process

Let $X_t$ be a stochastic process in $\mathbb{C}^n$ such that $$ dX_t = a(X_t,t)dt + b(X_t,t)dW_t.$$ And let $f:\mathbb{C}^n \to \mathbb{C}$. Then how to compute $df(X_t)$ in complex? If $f$ is a ...

Short examples that are/are not quantum-ergodic

Are there any considerably short examples of manifolds that are/aren't quantum ergodic, or quantum unique ergodic? Note that a (compact) Riemannian manifold is said to be quantum ergodic if almost ...

Three body problem with point interactions

I've studied the HVZ theorem for the three body problem interacting with regular potentials. I'd like to extend this result to the three body problem with point interactions (delta potentials). Is ...

Are there any theorems that can only be explained by analogies requiring knowledge of quantum mechanics?

The theorems I’ve seen in analysis can be explained by analogies that invoke the macroscopic visible world, areas, volumes, life sized physical things in sets. Are there any theorems in math that if ...
