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.

A teen forger and thief forms a criminal crew from her high school friends (and crush) to perform a series of heists leading to the location of her missing mother in this action-packed contemporary YA novel, The Con Code. By day, seventeen-year-old Fiona Spangler runs small cons for her ritzy prep-school classmates: getting them out of tests and forging fake hall passes. But by night, Fiona joins her dad on riskier heists: stealing back the clue-filled forgeries her mom scattered across the country before she disappeared. Fiona desperately hopes that her mother will be waiting at the end of the scavenger hunt she left behind. And they are SO close. Just three more heists remain, but then disaster strikes when Fiona’s dad is captured by the FBI. Desperate to finish the job and save what’s left of her family, Fiona assembles of crew of teen criminals: a master of disguise who can transform into anyone, a talented hacker who only communicates in glares, and a rival con artist with a vendetta against—and possible crush on—Fiona. All they have to do is perform three nearly impossible heists, solve her mother’s incredibly complex clues, and evade the FBI. Easy, right? Praise for Shana Silver's Mind Games: “An edge-of-your-seat thriller that will keep readers guessing. The complex plot, the occasional twists, and the quick pacing make this a difficult read to put down.” —School Library Journal "It's a YA Michael Crichton novel, minus the 100-page master class intro on quantum mechanics, biotech, and string theory...Mind Games is an absolute blast. If you are a fan of Memento or Strange Days, this one's definitely for you!" —NPR

It was 1798 when the Morningstarr twins arrived in New York with a vision for a magnificent city: towering skyscrapers, dazzling machines, and winding train lines, all running on technology no one had ever seen before. Fifty-seven years later, the enigmatic architects disappeared, leaving behind for the people of New York the Old York Cipher--a puzzle laid into the shining city they constructed, at the end of which was promised a treasure beyond all imagining. By the present day, however, the puzzle has never been solved, and the greatest mystery of the modern world is little more than a tourist attraction. Tess and Theo Biedermann and their friend Jaime Cruz live in a Morningstarr apartment--until a real estate developer announces that the city has agreed to sell him the five remaining Morningstarr buildings. Their likely destruction means the end of a dream long held by the people of New York. And if Tess, Theo, and Jaime want to save their home, they have to prove that the Old York Cipher is real. Which means they have to solve it.

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.

"An exquisitely timed book ... Code Red is a worthwhile exploration of the shared goals (and shared enemies) that unite moderates and progressives. But more than that, it is a sharp reminder that the common ground on which Dionne built his career has been badly eroded, with little prospect that it will soon be restored.” —The New York Times Book Review New York Times bestselling author and Washington Post columnist E. J. Dionne, Jr. sounds the alarm in Code Red, calling for an alliance between progressives and moderates to seize the moment and restore hope to America’s future for the 2020 presidential election. Will progressives and moderates feud while America burns? Or will these natural allies take advantage of the greatest opportunity since the New Deal Era to strengthen American democracy, foster social justice, and turn back the threats of the Trump Era? The United States stands at a crossroads. Broad and principled opposition to Donald Trump’s presidency has drawn millions of previously disengaged citizens to the public square and to the ballot boxes. This inspired and growing activism for social and political change hasn’t been seen since the days of Franklin Roosevelt’s New Deal policies and the Progressive and Civil Rights movements. But if progressives and moderates are unable—and unwilling—to overcome their differences, they could not only enable Trump to prevail again but also squander an occasion for launching a new era of reform. In Code Red, award-winning journalist E. J. Dionne, Jr., calls for a shared commitment to decency and a politics focused on freedom, fairness, and the future, encouraging progressives and moderates to explore common ground and expand the unity that brought about Democrat victories in the 2018 elections. He offers a unifying model for furthering progress with a Politics of Remedy, Dignity, and More: one that solves problems, resolve disputes, and moves forward; that sits at the heart of the demands for justice by both long-marginalized and recently-displaced groups; and that posits a positive future for Americans with more covered by health insurance, more with decent wages, more with good schools, more security from gun violence, more action to roll back climate change. Breaking through the partisan noise and cutting against conventional wisdom to provide a realistic look at political possibilities, Dionne offers a strategy for progressives and moderates to think more clearly and accept the responsibilities that history now imposes on them. Because at this point in our national story, change can’t wait.
