The quantum mechanics and the theory of the operators in the space of Hilbert have been seen deeply tie from their beginnings in century XX. States of a quantum system correspond to certain elements of the configuration space and observable they correspond to certain operators in the space. This book is a brief one, but in itself, introduction to the mathematical methods of the quantum mechanics, with a view to applications to the operators of Schrodinger. Part 1 of the book is a concise introduction to the spectral theory of operators nonlimited. Only the subjects that will be necessary for the later applications are covered. The spectral theorem is a central subject in this exposition and it is introduced in an early stage. Part 2 begins with the equation of free Schrodinger and calculates the free resolvente evolution and the time. Position, moment and angular momentum are discussed through the algebraic methods. Several are the developed mathematical methods, that soon are used to calculate the phantom of the hydrogen atom. Other subjects include nondegeneracy of the normal state, the phantoms of atoms, and the theory of the dispersion. This book serves like a car-contained introduction as the spectral theory as operators nonlimited in the space as Hilbert with complete demonstrations and requisite minimums: Only a solid knowledge of advanced calculation and an introduction of a semester to the complex analysis are obligatory. In particular, any functional analysis and theory of the integration of Lebesgue are not assumed. It is developed the mathematical instruments necessary to prove some key results in nonrelativistic the quantum mechanics. " Mathematical methods in Cuántica" Mechanics; it is destined for the beginning of the postgraduate students, as much in the mathematics and the physics and provides a solid base for the book reading and Literature more outpost the present investigation. Very it is adapted for the personal study and it includes numerous exercises (many of them with notes).
