Описание: Proposing a rigorous mathematical definition of the physical concept of a particle, this book obtains a concrete image of a particle conceived as a localised entity in space. It is intended for researchers and postgraduate students in operator theory, system theory, quantum physics and algebraic geometry.

Описание: Our goal is to find Grabner bases for polynomials in four different sets of expressions: 1 x-, (1 - x)-1 (RESOL) X, 1 x- (1 - xy)-1 (EB) X, y-1, (1-yx)-1 y, (1_y)-1 (1-x)-1 (preNF) (EB) plus and (1 - xy)1/2 (1 - yx )1/2 (NF) (preNF) plus and Most formulas in the theory of the Nagy-Foias operator model NF] are polynomials in these expressions where x = T and y = T*. Complicated polynomials can often be simplified by applying "replacement rules". For example, the polynomial (1 - xy)-2 - 2xy(1-xy)-2 + xy2 (1 - xy)-2 -1 simplifies to O. This can be seen by three applications of the replacement rule (1-xy) -1 xy -t (1 - xy)-1 -1 which is true because of the definition of (1-xy)-1. A replacement rule consists of a left hand side (LHS) and a right hand side (RHS). The LHS will always be a monomial. The RHS will be a polynomial whose terms are "simpler" (in a sense to be made precise) than the LHS. An expression is reduced by repeatedly replacing any occurrence of a LHS by the corresponding RHS. The monomials will be well-ordered, so the reduction procedure will terminate after finitely many steps. Our aim is to provide a list of substitution rules for the classes of expressions above. These rules, when implemented on a computer, provide an efficient automatic simplification process. We discuss and define the ordering on monomials later.
The field of urban economics is built on an analysis of housing prices, land rents, housing consumption, spatial form, and other aspects of urban residential structure. Drawing on the journal publications and teaching notes of Professor John Yinger of Syracuse University, Housing and Commuting: The Theory of Urban Residential Structure presents a simple model of urban residential structure and shows how the model's results change when key assumptions are made more realistic. This book provides a wide-ranging introduction to research on urban residential structure. Topics covered range from theoretical analysis of urban structure with different transportation systems or multiple worksites to empirical work on the impact of local public services on house values and the impact of racial prejudice and discrimination on housing choices. Graduate students and scholars who want to learn about research in urban economics will find this book to be a good starting point.

Описание: `Euro-commuters` have emerged as a new group of migrants since the onset of the economic crisis in the EU. These people work in one country but live in another. This book analyses the characteristics of these migrants, their motivations and how commuting influences their personal, family and social lives.

Описание: As a young man in New York City, he was a constant user of the New York City subway system. For a relatively small sum, one can spend the whole day and night in an underground world (growing up in New York often makes one think that the whole world is contained in its five boroughs).

Описание: This bookpresents recent results on positivity and optimization of polynomials innon-commuting variables. Researchers in non-commutative algebraic geometry,control theory, system engineering, optimization, quantum physics andinformation science will find the unified notation and mixture of algebraicgeometry and mathematical programming useful. Theoretical results are matchedwith algorithmic considerations; several examples and information on how to useNCSOStools open source package to obtain the results provided. Results arepresented on detecting the eigenvalue and trace positivity of polynomials innon-commuting variables using Newton chip method and Newton cyclic chip method,relaxations for constrained and unconstrained optimization problems, semidefiniteprogramming formulations of the relaxations and finite convergence of thehierarchies of these relaxations, and the practical efficiency of algorithms.

Описание: The conjugate operator method is a powerful technique for studying spectral properties of self-adjoint operators. This book presents a refinement of the original method due to Mourre leading to essentially optimal results in situations as varied as ordinary differential operators, pseudo-differential operators and N-body Schrodinger hamiltonians.
