Fri Jun 09, 2023An analysis-algebra problem that starts very quietly with the first 8 questions, then goes on with sequences of functions with values in \(R_n[X]\) whose coefficients are sums of integer series. Lots of algebra in the final section. The main difficulty of …

Mon Jun 05, 2023A difficult, demanding and very long algebra problem, which studies the quaternion field : matrix representation, descriptions of direct orthogonal endomorphisms, automorphisms. Many topics that are less frequently covered in other competitive exams: 1st y…

Thu Jun 01, 2023An analysis-algebra problem that studies the stability conditions of the following differential equation \[ \left\{ \begin{array}{ll} y'=\varphi(y)& \\ y(0)=x_0& \end{array} \right. \] where \(\varphi\) is a \(C^1\) map from \(\mathbb{R}^n\) to \(…

Tue May 30, 2023A rather interesting analysis problem that studies the Wallis function: \[ \begin{alignat*}{1} f:]-1,+\infty[&\to\mathbb{R}^{+*}\\ x&\mapsto \int_0^{\frac{\pi}{2}}(\sin t)^x \mathrm{d} t \end{alignat*} \] which is a generalization of the well-known integ…

Fri May 26, 2023A very long algebra problem set on polynomials and umbral calculus. At the heart of this formalism is the Pincherle derivation. We introduce the operator \(\mathbf{x}\) which is an endomorphism of polynomials: \[ \begin{alignat*}{1} \mathbf{x}:\math…
