Acid reflux, or the backflow of stomach acid into the esophagus, throat or mouth, is the most noticeable symptom of gastroesophageal reflux disease (GERD). This chronic condition can have serious consequences if left untreated. Fortunately, most cases of acid reflux respond well to treatment with a combination of lifestyle changes and medication. Surgical procedures may also provide relief. If you are experiencing symptoms of GERD, which include heartburn, regurgitation of stomach acid, coughing, postnasal drip, difficulty swallowing and even excessive erosion of tooth enamel, follow these suggestions for how to treat acid reflux.
The root discriminant of a number field, K , of degree n , often denoted rd K , is defined as the n -th root of the absolute value of the (absolute) discriminant of K .  The relation between relative discriminants in a tower of fields shows that the root discriminant does not change in an unramified extension. The existence of a class field tower provides bounds on the root discriminant: the existence of an infinite class field tower over Q (√-m) where m = 3·5·7·11·19 shows that there are infinitely many fields with root discriminant 2√ m ≈ .  If we let r and 2 s be the number of real and complex embeddings, so that n = r + 2 s , put ρ = r / n and σ = 2 s / n . Set α ( ρ , σ ) to be the infimum of rd K for K with ( r', 2 s') = ( ρn , σn ). We have (for all n large enough)
