Andreas Floer died on may possibly 15, 1991 an premature and tragic loss of life. His visions and far-reaching contributions have considerably encouraged the advancements of arithmetic. His major pursuits established at the fields of dynamical platforms, symplectic geometry, Yang-Mills thought and occasional dimensional topology. prompted by means of the worldwide lifestyles challenge of periodic recommendations for Hamiltonian structures and ranging from rules of Conley, Gromov and Witten, he constructed his Floer homology, delivering new, robust tools which are utilized to difficulties inaccessible just a couple of years in the past. This quantity opens with a quick biography and 3 hitherto unpublished papers of Andreas Floer. It then provides a set of invited contributions, and survey articles in addition to study papers on his fields of curiosity, bearing testimony of the excessive esteem and appreciation this amazing mathematician loved between his colleagues. Authors comprise: A. Floer, V.I. Arnold, M. Atiyah, M. Audin, D.M. Austin, S.M. Bates, P.J. Braam, M. Chaperon, R.L. Cohen, G. Dell' Antonio, S.K. Donaldson, B. D'Onofrio, I. Ekeland, Y. Eliashberg, K.D. Ernst, R. Finthushel, A.B. Givental, H. Hofer, J.D.S. Jones, I. McAllister, D. McDuff, Y.-G. Oh, L. Polterovich, D.A. Salamon, G.B. Segal, R. Stern, C.H. Taubes, C. Viterbo, A.

Throughout the educational 12 months 1995/96, i used to be invited by means of the Scuola Normale Superiore to provide a chain of lectures. the aim of those notes is to make the underlying fiscal difficulties and the mathematical thought of external differential platforms available to a bigger variety of humans. it's the objective of those notes to move over those effects at a extra leisurely velocity, preserving in brain that mathematicians will not be accustomed to monetary thought and that only a few humans have learn Elie Cartan.

Read e-book online Space-Time Algebra PDF

By David Hestenes, Anthony Lasenby

Initially released via Gordon and Breach technology Publishers, ny, 1966

Spacetime Algebra (STA) offers a unified, coordinate-free mathematical framework for either classical and quantum physics
STA reduces electrodynamics to a unmarried Maxwell equation with specific kinship to Dirac's equation
STA unearths hidden geometric constitution in Dirac’s equation with new perception into the position of advanced numbers in quantum mechanics
STA deals a singular gauge idea method of quantum mechanics and normal Relativity

This small booklet all started a profound revolution within the improvement of mathematical physics, one that has reached many operating physicists already, and which stands poised to result in far-reaching swap within the future.

At its middle is using Clifford algebra to unify differently disparate mathematical languages, fairly these of spinors, quaternions, tensors and differential kinds. It presents a unified procedure overlaying these kinds of parts and therefore ends up in a truly effective ‘toolkit’ to be used in actual difficulties together with quantum mechanics, classical mechanics, electromagnetism and relativity (both detailed and common) – just one mathematical process has to be discovered and understood, and you can still use it at degrees which expand all over to present study themes in each one of those components.

These related thoughts, within the type of the ‘Geometric Algebra’, could be utilized in lots of components of engineering, robotics and laptop technology, with out adjustments important – it's the related underlying arithmetic, and permits physicists to appreciate issues in engineering, and engineers to appreciate themes in physics (including facets in frontier areas), in a fashion which no different unmarried mathematical procedure may well wish to make possible.

There is one other element to Geometric Algebra, that is much less tangible, and is going past questions of mathematical energy and diversity. this can be the amazing perception it offers to actual difficulties, and how it consistently indicates new positive aspects of the physics itself, not only the math. Examples of this are peppered all through ‘Space-Time Algebra’, regardless of its brief size, and a few of them are successfully nonetheless learn subject matters for the future.
