Vor 4 Tagen · It formalizes the intuitive idea that primes become less common as they become larger by precisely quantifying the rate at which this occurs. The theorem was proved independently by Jacques Hadamard and Charles Jean de la Vallée Poussin in 1896 using ideas introduced by Bernhard Riemann (in particular, the Riemann zeta function).
Vor einem Tag · In 1898, Jacques Hadamard published an influential study of the chaotic motion of a free particle gliding frictionlessly on a surface of constant negative curvature, called "Hadamard's billiards". Hadamard was able to show that all trajectories are unstable, in that all particle trajectories diverge exponentially from one another ...
Vor 2 Tagen · The Hadamard or Walsh-Hadamard gate, named after Jacques Hadamard (French:) and Joseph L. Walsh, acts on a single qubit. It maps the basis states | 0 ↦ | 0 + | 1 2 {\textstyle |0\rangle \mapsto {\frac {|0\rangle +|1\rangle }{\sqrt {2}}}} and | 1 ↦ | 0 − | 1 2 {\textstyle |1\rangle \mapsto {\frac {|0\rangle -|1\rangle }{\sqrt {2 ...
Vor 3 Tagen · Definition of well-posed problem was first proposed in 1902 by the French mathematician Jacques Hadamard (1865--1963) in the framework on partial differential equations. Problems that are not well-posed in the sense of Hadamard are termed ill-posed.

9. Mai 2024 · Their work attracted quite a bit of attention with full support of the famous French mathematician Jacques Hadamard (1865--1963). They put mathematical foundation into van der Pol experimental research.
13. Mai 2024 · He served as deputy director of École doctorale Jacques Hadamard before becoming the director of CMAP in 2020, following Anne de Bouard. Thierry Bodineau is a mathematician specializing in probability theory, and his work focuses on problems related to statistical mechanics.
