David Hernandez – författare

For a life to come together, sometimes it first has to fall completely apart.

Isabel is a regular seventeen-year-old girl, still reeling from the pain of her boyfriend''s tragic death exactly one year ago.

Carlos is a regular seventeen-year-old guy, loves red licorice and his friends, and works at a fancy art museum for some extra cash.

The two have no connection until they both meet Vanessa, an intriguing new transfer student with a mysterious past. While Vanessa is the link that brings these two very different lives together, will she be the one that can also tear them apart?

In his stunningly beautiful second novel, David Hernandez gives his readers a poetic and profound story that tells of two completely different teenagers and how through everyday life and monumental tragedy lies endless possibility.

It''s the summer before senior year, and Marcus should be hanging out, filling his sketchbook, maybe asking a girl out for once. So why is he in a car with his brother, his brother''s girl, and the pistol, headed straight toward his dad?

David Hernandez writes with striking lyricism and unfaltering poise. Suckerpunch marks the debut of a superb and important new literary talent.

This textbook provides an undergraduate introduction to Galois theory and its most notable applications.

Galois theory was born in the 19th century to study polynomial equations. Both powerful and elegant, this theory was at the origin of a substantial part of modern algebra and has since undergone considerable development. It remains an extremely active research subject and has found numerous applications beyond pure mathematics. In this book, the authors introduce Galois theory from a contemporary point of view. In particular, modern methods such as reduction modulo prime numbers and finite fields are introduced and put to use. Beyond the usual applications of ruler and compass constructions and solvability by radicals, the book also includes topics such as the transcendence of e and π, the inverse Galois problem, and infinite Galois theory.

Based on courses of the authors at the École Polytechnique, the book is aimed at students with a standard undergraduate background in (mostly linear) algebra. It includes a collection of exam questions in the form of review exercises, with detailed solutions.
