There are connections between invariant theory and modular forms since the times of Felix Klein, in the 19th century, connections between codes and lattices since the 1960's. The aim of the book is to explore the interplay between codes and modular forms. Here modular form is understood in a wide sense (Jacobi forms, Siegel forms, Hilbert forms). Codes comprises not only linear spaces over finite fields but modules over some commutative rings. The connection between codes over finite fields and lattices has been well documented since the 1970s. Due to an avalanche of results on codes over rings since the 1990's there is a need for an update at book level.

The #1 nationally bestselling Warriors series continues! Discover more epic adventures in the fourth book in the action-packed Broken Code story arc. Exiled after a battle that left all five Clans devastated, ThunderClan's loyal deputy, Squirrelflight, must bring to light an earth-shattering truth: the identity of the cat ruling ThunderClan while wearing Bramblestar's face. While the fate of his body hangs in the balance, the real Bramblestar's spirit has vanished. Even Rootspring is powerless to reach him--and with tensions among the Clans at a breaking point, Squirrelflight may not be able to ensure Bramblestar has a body to return to. If he returns at all. Packed with action and intrigue, this sixth Warriors series is the perfect introduction for readers new to the Warriors world, while dedicated fans will be thrilled to discover the new adventures that unfold after the events of A Vision of Shadows.

Mateo is an enforcer, a skilled killer in a world ruled by blood and power. But behind the hardened mask, a sliver of compassion remains. The lives he breaks are sacrifices to protect the one person left who depends on him. Every act of violence pushes him closer to the darkness, making him the monster he is paid to be. When one bloody job spirals out of control, he is betrayed. Now, Mateo is the hunted, on the run with not just his life on the line, but the hope that clings to his soul. But with enemies closing in and a past he can never fully outrun, Mateo must do more than survive. This is a tale of violence and despair, where the lines between right and wrong blur in the dust. It asks: Can a man forged by brutality rise above it? Is there an escape from a path stained red? Or are some destinies carved in bloodshed, with the only choices being who dies and who walks away scarred?

One of the most remarkable and beautiful theorems in coding theory is Gleason's 1970 theorem about the weight enumerators of self-dual codes and their connections with invariant theory, which has inspired hundreds of papers about generalizations and applications of this theorem to different types of codes. This self-contained book develops a new theory which is powerful enough to include all the earlier generalizations.
