Lagrangian shadows and triangulated categories
by Paul Biran, Octav Cornea, Egor Shelukhin (2021)
About this book
We introduce new metrics on spaces of Lagrangian submanifolds, not necessarily in a fixed Hamiltonian isotopy class. Our metrics arise from measurements involving Lagrangian cobordisms. We also show that splitting Lagrangians through cobordism has an energy cost and, from this cost being smaller than certain explicit bounds, we deduce some forms of rigidity of Lagrangian intersections. We also fit these constructions in the more general algebraic setting of triangulated categories, independent of Lagrangian cobordism. As a main technical tool, we develop aspects of the theory of (weakly) filtered A∞-categories.

Lectures on non-linear plasma kinetics
Vadim N. Tsytovich
"Lectures on Nonlinear Plasma Kinetics" is an introduction to modern non-linear plasma physics showing how many of the techniques of modern non-linear physics find applications in plasma physics and how, in turn, the results of this research find applications in astrophysics. Emphasis is given to explaining the physics of nonlinear processes and the radical change of cross-sections by collective effects. The author discusses new nonlinear phenomena involving the excitation of coherent nonlinear structures and the dynamics of their random motions in relation to new self-organization processes. He also gives a detailed description of applications of the general theory to various research fields, including the interaction of powerful radiation with matter, collective laser particle accelerators, controlled thermonuclear research, space physics, solar physics, and astrophysics.
Star Wars - Black Fleet Crisis - Tyrant's Test
Michael P. Kube-McDowell
In the wake of a shattered alliance, the New Republic fights a relentless new enemy in an all-new adventure in the bestselling Star Wars saga… Faced with an alarming image of Han as a battered hostage of the Yevetha, Chewbacca takes on an urgent mission. Meanwhile, Leia calls upon the Senate to take a stand and eliminate the Yevetha threat—even at the cost of Han's life. As a former Imperial governor takes his battle to the runaway Qella spaceship, Luke's continuing search for his mother brings him dangerously close to Nil Spaar's deadly forces. And as the Yevetha close in on the forces of the New Republic, Luke takes a desperate gamble with an invisible weapon....
Holographic Interferometry
Pramod K. Rastogi
Holographic Interferometry provides a valuable and up-to-date source of information in the rapidly expanding field. The eight specialists` contributions cover the principles and methods currently in use. The scope of the book has been limited to the study of opaque object and ample space has been devoted to a comprehensive treatment of the phenomena of fringe formation, with a particular emphasis on the quantitative evaluation of the holographic interference fringe patterns. The emergence of computer-aided fringe analysis and phase-shifting techniques have simplified considerably the quantative real-time measurements of object shapes and deformations. The last two chapters provide a reasonably detailedoverview of full-field holographic methods for the measurement of shapes, displacements, dervatives, difference displacements and vibrations.
