In theoretical physics, a cascading gauge theory is a gauge theory whose coupling rapidly changes with the scale in such a way that Seiberg duality must be applied many times. Klebanov and Strassler studied this kind of N=1 gauge theory in the context of the AdS-CFT correspondence, which is dual to the warped deformed conifold.
Famous quotes containing the words cascading and/or theory:
“Have We not made the earth as a cradle and the mountains as pegs? And We created you in pairs, and We appointed your sleep for a rest; and We appointed night for a garment, and We appointed day for a livelihood. And We have built above you seven strong ones, and We appointed a blazing lamp and have sent down out of the rain-clouds water cascading that We may bring forth thereby grain and plants, and gardens luxuriant.”
—Qur’An. “The Tiding,” 78:6-16, trans. by Arthur J. Arberry (1955)
“We have our little theory on all human and divine things. Poetry, the workings of genius itself, which, in all times, with one or another meaning, has been called Inspiration, and held to be mysterious and inscrutable, is no longer without its scientific exposition. The building of the lofty rhyme is like any other masonry or bricklaying: we have theories of its rise, height, decline and fall—which latter, it would seem, is now near, among all people.”
—Thomas Carlyle (1795–1881)
