What is the meaning of duality?

Definition of duality : the quality or state of having two different or opposite parts or elements : dualism That duality—sophistication paired with authenticity on the wine list, simplicity spiced with creativity on the menu—gives Marea energy and distinctive character.

How do you preserve duality in the presence of sources?

In the presence of sources, duality is preserved provided that we include both electricandmagnetic sources: @”F „”=j”@ F„”=k„; and that we supplement the duality transformations (1.4) by a similar trans- formation of the sources:

Is the classical spectrum of the model invariant under electromagnetic duality?

We show that the classical spectrum of the model is invariant under electromagnetic duality. This leads to the conjecture of Montonen and Olive. We then discuss he Witten efiect” and show that the Z2electromagnetic duality extends to anSL(2;Z) duality. 1.1 The Dirac Monopole

What is the Montonen{Olive duality?

In this chapter we treat classical electromagnetic duality, and its manifesta- tion (Montonen{Olive duality) in some spontaneously broken gauge theories. We start by reviewing the Dirac monopole, and then quickly move on to the ’t Hooft{Polyakov monopole solution in the model described by the bosonic part of theSO(3) Georgi{Glashow model.

When was Dualit founded?

Dualit was founded in 1945 by the German-born inventor Max Gort-Barten CBE (1914–2003) and was incorporated as Dualit Ltd in 1948.

What products does Dualit make?

Dualit diversified its product range to include kitchen appliances such as blenders, juicers and non-kitchen products like pedestal fans and hand dryers. Dualit still produce a comprehensive range of catering products, together with several toaster and kettle collections, a food preparation range and coffee and tea machines.
