Stalingrad
“A fresh look at what is perhaps the most famous battle of the Russo-German War from the Soviet perspective.” —The NYMAS Review Much has been written about the Battle of Stalingrad, the Soviet victory that turned the tide of the Second World War. Yet our knowledge and understanding continues to evolve, and this engrossing account by Alexey Isaev brings together previously unpublished Russian archive material—strategic directives and orders, after-action reports, and official records of all kinds—with the vivid recollections of soldiers who were there, on the front lines, reconstructing what happened in extraordinary new detail. The evidence leads him to question common assumptions ...
Hitler's Fortresses in the East
‘Fortresses must carry out the same tasks as the fortresses of old....They must allow themselves to be surrounded and thus tie down as many enemy forces as possible.’ So Hitler directed in March 1944 and, in so doing, sealed the fate of Ternopol', Kovel', Poznan and Breslau, cities in the Ukraine and Poland that were in the path of the Red Army’s advance towards Nazi Germany. German forces, under orders to resist at all costs, adopted all-round defence and struggled to hold out while waiting for relief – which never came. In this gripping and original book, Alexey Isaev describes, in vivid detail, what happened next –intense and ruthless fighting, horrendous casualties among soldie...
Spinors, Twistors, Clifford Algebras and Quantum Deformations
ZBIGNIEW OZIEWICZ University of Wroclaw, Poland December 1992 The First Max Born Symposium in Theoretical and Mathematical Phy sics, organized by the University of Wrodaw, was held in September 1991 with the intent that it would become an annual event. It is the outgrowth of the annual Seminars organized jointly since 1972 with the University of Leipzig. The name of the Symposia was proposed by Professor Jan Lopu szanski. Max Born, an outstanding German theoretical physicist, was born in 1883 in Breslau (the German name of Wrodaw) and educated here. The Second Max Born Symposium was held during the four days 24- 27 September 1992 in an old Sobotka Castle 30 km west of Wrodaw. The Sobotka Castle was built in the eleventh century. The dates engraved on the walls of the Castle are 1024, 1140, and at the last rebuilding, 1885. The castle served as a cloister until the end of the sixteenth century.
Quantum Theory and Symmetries with Lie Theory and Its Applications in Physics Volume 1
This book is the first volume of proceedings from the joint conference X International Symposium “Quantum Theory and Symmetries” (QTS-X) and XII International Workshop “Lie Theory and Its Applications in Physics” (LT-XII), held on 19–25 June 2017 in Varna, Bulgaria. The QTS series was founded on the core principle that symmetries underlie all descriptions of quantum systems. It has since evolved into a symposium at the forefront of theoretical and mathematical physics. The LT series covers the whole field of Lie theory in its widest sense, together with its applications in many areas of physics. As an interface between mathematics and physics, the workshop serves as a meeting place...
Don't Tell the Boss!
After a major disaster, when investigators are piecing together the story of what happened, a striking fact often emerges: before disaster struck, some people in the organization involved were aware of dangerous conditions that had the potential to escalate to a critical level. But for a variety of reasons, this crucial information did not reach decision-makers. So, the organization moved ever closer to catastrophe, effectively unaware of the possible threat—despite the fact that some of its employees could see it coming. What is the problem with communication about risk in an organization, and why does this problem exist? What stops people in organizations or project teams from freely rep...
Lie Theory and Its Applications in Physics
This volume presents modern trends in the area of symmetries and their applications based on contributions to the workshop "Lie Theory and Its Applications in Physics" held near Varna (Bulgaria) in June 2019. Traditionally, Lie theory is a tool to build mathematical models for physical systems. Recently, the trend is towards geometrization of the mathematical description of physical systems and objects. A geometric approach to a system yields in general some notion of symmetry, which is very helpful in understanding its structure. Geometrization and symmetries are meant in their widest sense, i.e., representation theory, algebraic geometry, number theory, infinite-dimensional Lie algebras an...
Sugawara Operators for Classical Lie Algebras
The celebrated Schur-Weyl duality gives rise to effective ways of constructing invariant polynomials on the classical Lie algebras. The emergence of the theory of quantum groups in the 1980s brought up special matrix techniques which allowed one to extend these constructions beyond polynomial invariants and produce new families of Casimir elements for finite-dimensional Lie algebras. Sugawara operators are analogs of Casimir elements for the affine Kac-Moody algebras. The goal of this book is to describe algebraic structures associated with the affine Lie algebras, including affine vertex algebras, Yangians, and classical -algebras, which have numerous ties with many areas of mathematics and mathematical physics, including modular forms, conformal field theory, and soliton equations. An affine version of the matrix technique is developed and used to explain the elegant constructions of Sugawara operators, which appeared in the last decade. An affine analogue of the Harish-Chandra isomorphism connects the Sugawara operators with the classical -algebras, which play the role of the Weyl group invariants in the finite-dimensional theory.

Quantum Theory and Symmetries with Lie Theory and Its Applications in Physics Volume 2
This book is the second volume of the proceedings of the joint conference X. International Symposium “Quantum Theory and Symmetries” (QTS-X) and XII. International Workshop “Lie Theory and Its Applications in Physics” (LT-XII), 19–25 June 2017, Varna, Bulgaria. The QTS series started around the core concept that symmetries underlie all descriptions of quantum systems. It has since evolved into a symposium on the frontiers of theoretical and mathematical physics. The LT series covers the whole field of Lie Theory in its widest sense together with its applications in many facets of physics. As an interface between mathematics and physics the workshop serves as a meeting place for mat...
