Linear Systems

In response to a streamlined presentation of the authors' winning paintings Linear platforms, this textbook offers an creation to structures conception with an emphasis on regulate. the fabric awarded is vast adequate to provide the reader a transparent photo of the dynamical habit of linear structures in addition to their benefits and boundaries.

Statistical and Computational Inverse Problems (Applied Mathematical Sciences)

This e-book covers the statistical mechanics method of computational answer of inverse difficulties, an leading edge region of present study with very promising numerical effects. The thoughts are utilized to a few genuine global functions equivalent to restricted perspective tomography, photo deblurring, electical impedance tomography, and biomagnetic inverse difficulties.

Wavelets and Subbands: Fundamentals and Applications

Lately there was excessive learn job almost about wavelet and subband thought. specialists in assorted fields equivalent to arithmetic, physics, electric engineering, and picture processing have supplied unique and pioneering works and effects. yet this range, whereas wealthy and efficient, has ended in a feeling of fragmentation, specially to these new to the sector and to nonspecialists who're attempting to comprehend the connections among the several points of wavelet and subband idea.

Fitted Numerical Methods For Singular Perturbation Problems: Error Estimates in the Maximum Norm for Linear Problems in One and Two Dimensions

Because the first variation of this e-book, the literature on equipped mesh equipment for singularly perturbed difficulties has improved considerably. Over the intervening years, geared up meshes were proven to be powerful for an in depth set of singularly perturbed partial differential equations. within the revised model of this e-book, the reader will locate an creation to the fundamental thought linked to geared up numerical tools for singularly perturbed differential equations.
