How does arbitrage relate to the law of one price?
The law of one price states that in the absence of friction between global markets, the price for any asset will be the same. The law of one price is achieved by eliminating price differences through arbitrage opportunities between markets. Market equilibrium forces would eventually converge the price of the asset.

What is the no arbitrage principle?
Derivatives are priced using the no-arbitrage or arbitrage-free principle: the price of the derivative is set at the same level as the value of the replicating portfolio, so that no trader can make a risk-free profit by buying one and selling the other.
What is absence of arbitrage?

Who invented arbitrage pricing theory?
The Arbitrage Pricing Theory (APT) was developed primarily by Ross (1976a, 1976b). It is a one-period model in which every investor believes that the stochastic properties of returns of capital assets are consistent with a factor structure.
How do you test the law of one price?
Effective arbitrage imposes at least 3 conditions on the transactions used in a valid test of the law of one price: (1) Products must be identical. (2) Resale must be possible. (3) There is no risk.
