Un extrano objeto llega a la Tierra. Su aparicion provoca un profundo desasosiego. Se lo conoce como la nada. A pesar de su desagradable presencia, emite un criptico mensaje de esperanza: alguien tendra todas las respuestas en siete dias.
Al mismo tiempo, Mama Irma, Ada y Grace, empiezan a ver como su mundo cambia drasticamente. Sus destinos, aunque no lo sepan, estan condenados a encontrarse. Mientras, la humanidad se adentra en un momento de cambio sin precedentes; es posible que sus ultimas preguntas sean respondidas…
Despierta. Es el momento de la disrupcion.
Banach, Frechet, Hilbert and Neumann Spaces

Год издания:
This book is the first of a set dedicated to the mathematical tools used in partial differential equations derived from physics. Its focus is on normed or semi-normed vector spaces, including the spaces of Banach, Frechet and Hilbert, with new developments on Neumann spaces, but also on extractable spaces. The author presents the main properties of these spaces, which are useful for the construction of Lebesgue and Sobolev distributions with real or vector values and for solving partial differential equations. Differential calculus is also extended to semi-normed spaces. Simple methods, semi-norms, sequential properties and others are discussed, making these tools accessible to the greatest number of students – doctoral students, postgraduate students – engineers and researchers without restricting or generalizing the results.
