  • Solve $x^2y''+xy'+m^2x^{2m}y=0$ with a substitution
    I have the differential equation $x^2y''+xy'+m^2x^{2m}y=0$ where $x>0$ and $m\neq 0$. I know a general method to solve this kind of equation with Bessel functions: $$x^2y''+(2p+1)xy'+(a^2x^{2r}+b^2)y=0 \Rightarrow y=x^{-p}\Big( c_1J_{q/r}(\frac{a}{r}x^r) + c_2Y_{q/r}(\frac{a}{r}x^r ) \Big)$$ where $q=\sqrt{p^2-b^2}$ so my equation is solved for $y=c_1J_0(x^m)+c_2Y_0(x^m)$. Is it possible to get the same solution without the previous formula? I've […]
  • Differential equation of monomials -- finding singularities
    I have a 2-dimensional system of differential equations of the following form: $$ \frac{dx}{dt} = x(t)^{a+b} y(t)^a \\ \frac{dy}{dt} = x(t)^c y(t)^{c+d} $$ Denoting $Z=[x,y]'$ and taking logs, we can write $$ \ln \left( \frac{dZ}{dt} \right) = A \ln (Z(t)) $$ where the logs are taken element-wise and $$ A = \left( \begin{array} aa+b & […]
  • Proving that every first order differential equation with a general solution has an integrating factor
    My textbook claims that every first order differential equation of the form $$P(x,y)+Q(x,y)\cdot y'=0$$ has an integrating factor such that $$IP+IQ\cdot y'=0$$ is an exact differential equation. The proof (which is adapted from the same textbook) is given here: https://proofwiki.org/wiki/Existence_of_Integrating_Factor#:~:text=Then%20it%20is%20always%20possible,Solution%20to%20Exact%20Differential%20Equation. However, I am unable to follow several steps in the proof (division of the DE […]
  • General solution of a Bessel-like ODE
    I am trying to solve the ordinary differential equation \begin{equation*} t\frac{\mathrm{d}^{2}\theta}{\mathrm{d}t^{2}} + 2\frac{\mathrm{d}\theta}{\mathrm{d}t} + c\theta = 0 \end{equation*} [subject to $\theta(0) = \theta_{0}$ and $\theta'(0) = 0$, but I'd like to find a general solution] for $\theta(t)$, where $c>0$ is a constant, but I'm having trouble getting started. I know that the problem is soluble […]
  • How $D-f=e^{D^{-1}f}De^{-D^{-1}f}$ and $T-f=(T\prod f)\Delta(\prod f)^{-1}$ are connected
    I have just learnt how to convert an operator containing addition into chained operators so that its inversion can be computed explicitly, here is what I meant: Differential: $$D-f=e^{D^{-1}f}De^{-D^{-1}f}, (f =f(t))\tag{1}$$ Difference: $$T-f=(T\prod f)\Delta(\prod f)^{-1}, (f=f(n))\tag{2}$$ Explaining my symbols: $D=\frac{d}{dt}; D^{-1}=\int ()dt; T(x_{n})=x_{n+1}; \Delta(x_n)=x_{n+1}-x_{n}; \Delta^{-1}(x_{n})=C+\sum_{i=0}^{n-1} (x_{i}); \prod f(n)=\prod_{i=0}^{n-1}f(i)$ The only relation between differential operators and […]
  • Given that $\dot x_t = a [(2p-1) y_t + 1-p - f(x_t)], \dot y_t = -b [(2p-1) y_t + 1-p - f(x_t)]$ prove that if $a \gg b$, then $f(x_t) \rightarrow p$.
    I have a set of differential equations: \begin{align*} \dot x_t = a [(2p-1) y_t + 1-p - f(x_t)], \quad \dot y_t = -b [(2p-1) y_t + 1-p - f(x_t)] \end{align*} I know that $a, b > 0$, $ a \gg b$, $f(x) \in (0,1)$ is monotonically increasing, $p \in (1/2, 1)$, and that $y_0 = […]
  • Is there an ODE so that every solution is extensible?
    The following question arose while studying initial value problems of ODE with the form: \begin{align*}y'(t)&=f(t,y(t)),\\ y(t_0)&=y_0.\end{align*} A solution to an IVP above is a function $u:J\to \Omega$, where $J$ is an open interval and $\Omega\subseteq\mathbb{R}^n$ is an open set, which satisfies our IVP above. An extension is a solution to our IVP, $\overline{u}:\overline{J}\to\Omega$ where $\overline{J}$ […]
  • Using Bessel function definition to check the solution of $xy''+(x^2-2)y=0$
    I'm working on this exercise: Using the definition of the Bessel function $J_p(x)=\sum_{k=0}^{+\infty}\frac{(-1)^k}{k!\;\Gamma (k+p+1)}\Big(\frac{x}{2}\Big)^{2k+p}$ show that for $x>0$ the differential equation $xy''+(x^2-2)y=0$ has the general solution $y(x)=c_1x^{\frac{1}{2}}J_{\frac{3}{2}}(x)+c_2x^{\frac{1}{2}}J_{-\frac{3}{2}}(x)$. If $y(x)$ is a solution for every value of $c_1$ and $c_2$ I tried to define $c_1=1$ and $c_2=0$ and check if $y(x)=x^{\frac{1}{2}}J_{\frac{3}{2}}(x)$ is a solution. With the […]
  • Exponential of linear operator as solution to linear matrix ODE?
    For $X_0 \in \mathcal{M}_{n}(\mathbb{C}) $ and $A$ a linear operator from $\mathcal{M}_n(\mathbb{C}) $ to $\mathcal{M}_{n}(\mathbb{C})$. We consider the following matrix valued ODE problem : \begin{align*} X'(t) &= A[X(t)]\\ X(0) &= X_0 \end{align*} Can we say that the solution is given by $X(t) = \exp\{tA\}[X_0]$ ? Where $ \exp\{tA\}[Y] = \sum_{k=0}^{\infty}\frac{t^{k}A^{k}[Y]}{k!} $ ?
  • Uniqueness of center manifold in the analysis of a generic fold point.
    I am currently trying to understand the paper "Extending geometric singular perturbation theory to generic fold points" by Krupa and Szmolyan. There the following system of ODEs comes up. \begin{align} &x_1' = -1 + x_1^2 + \frac{1}{2}\varepsilon_1x_1 + \mathcal{O}(r_1) \\ &r_1' = \frac{1}{2}r_1\varepsilon_1(-1 + \mathcal{O}(r_1)) \\ &\varepsilon_1' = \frac{3}{2}(1 + \mathcal{O}(r_1)). \end{align} I am interested […]
