Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

A generalized Schur-type algorithm for the joint factorization of a structured matrix and its inverse

Ali H. Sayed

A Schur-type algorithm is presented for the simultaneous triangular factorization of a given (non-degenerate) structured matrix and its inverse. The algorithm takes the displacement generator of a Hermitian, strongly regular matrixR as an input, and comput ...

Ultrafast intramolecular and caging dynamics in solvents from frequency-domain experiments

Majed Chergui

A summary of results on the resonance Raman study of I2 in CCl4 and liq. Xe is presented. No discrete fluorescence can be obsd. upon excitation in the bound parts of the B state and instead a resonance Raman spectrum shows up superimposed on a broad fluore ...

Computing simulations on finite and infinite graphs

Monika Henzinger

We present algorithms for computing similarity relations of labeled graphs. Similarity relations have applications for the refinement and verification of reactive systems. For finite graphs, we present an O(mn) algorithm for computing the similarity relati ...

Iterative Toeplitz solvers with local quadratic convergence

Martin Vetterli

We study an iterative, locally quadratically convergent algorithm for solving Toeplitz systems of equations from [R. P. Brent, F. G. Gustavson and D. Y. Y. Yun. ''Fast solution of Toeplitz systems of equations and computation of Pade approximations'', J. A ...

Subband Renormalization in the Presence of a Dense Electron-Hole Plasma in a Quantum-Well

We calculate the shrinkage of the gaps between the two lowest subbands in a quantum well induced by the presence of a photo-excited electron-hole plasma. The results are reported as a function of well width and plasma concentration. The reduction of the hi ...
