- A difficult application of Feynman's integration method: $\int_0^\pi \ln(1+\alpha\cos x)dx$by Laplace's Demon on May 20, 2025 at 8:43 am
By differentiating with respect to $\alpha$, find the values of the following integrals: $$\int_0^\pi \ln(1+\alpha\cos x)dx\quad\text{and}\quad \int_0^1\frac{x^\alpha-1}{\ln x}dx.$$ (This is my first question on the site so forgive me if I make any mistakes) I've been trying to solve the first integral in the attachment for a while now, my problem is the definite integral of the derivative $ \cos x/ (1 + a \cos x)$, where "a" is the parameter, from $0$ to $pi$. I gave up yesterday and checked what the general solution was on Wolfram Alpha and it was definitely beyond what I was capable of. However, the second question was very easy, so I'm wondering if there was a trick involving the limits I missed out on for the first integral that would make it doable.
- Can any partition be realized by the intersection of algebraic curves?by Yalim O on May 20, 2025 at 8:32 am
According to Bézout's Theorem, two algebraic plane curves of degrees $d_1$ and $d_2$ intersect at $d_1 d_2 $ points when counted with multiplicities. Furthermore the multiplicity at each point is a positive number. Hence the multiplicities of the points give a partition of $ d_1 d_2 $. Can any partition of $ d_1 d_2$ be realized by intersecting smooth complex algebraic curves of degrees $d_1$ and $d_2$?
- Exponential of Paulistringby brave on May 20, 2025 at 8:28 am
For the Pauli matrices, the exponential is given by $ e^{i \theta \sigma} = \cos(\theta) + i \sin(\theta) \sigma $. If we have a tensor product of Pauli matrices $\otimes_{i=1}^{N} \sigma_i$, does the same formula still hold?
- Do random dynamical systems have similar properties?by Ann on May 20, 2025 at 8:21 am
Let $f:M \rightarrow M$ be a measurable transformation preserving a probability measure $\mu$, we denote the entropy of the system $(f,\mu)$ by $h_{\mu}f$. I know $h_{\mu}(f^k)=kh_{\mu}(f)$ for every $k\in \mathbb{N}$. Let $M$ be a compact metric space with the metric $d, \mathcal{B}$ the Borel $\sigma$-algebra of $M$. Let $(\Omega, \mathcal{F}, \mathbf{P}, \vartheta)$ be a probability space and $\vartheta$ is an invertible measure-preserving transformation. Let $C(M, M)$ be the space of continuous mappings of $M$, Let $$ F:(\Omega, \mathcal{F}, \mathbf{P}) \longrightarrow C(M, M), \omega \mapsto F(\omega)=: f_{\omega} $$ be a measurable map and define $$ f_{\omega}^{n}= \begin{cases}i d & \text { if } n=0 \\ f_{\vartheta^{n-1} \omega} \circ \cdots \circ f_{\vartheta \omega} \circ f_{\omega} & \text { if } n>0\end{cases} $$ Could you please tell me if random dynamical systems possess similar properties $h_{\mu}(f_{\omega}^k)=kh_{\mu}(f_{\omega})$?
- Every graph can be reduced to $\delta$-regular graph?by MathInquirer on May 20, 2025 at 8:10 am
Let $G$ be a finite graph with a minimum vertex degree $\delta(G)$. I'm conjecturing that there exists a way to reduce this graph to a $\delta(G)$-regular i.e a graph with all nodes having a degree of $\delta(G)$. By reducing, I mean we can find a subgraph with such property(vertices and edges are deletable). Is this provable? My attempt: Induction on either the number of edges or $\delta(G)$ fails. For example, in the first case, removing edges possibly reduce $\delta(G)$. So, by induction, we're only guaranteed a $n$-regular. It's hard to raise this to $n + 1$. Any idea?
