ABSTRACT

The notion of an asset (anything of value) is one of the fundamental notions in mathematical finance. Assets can be risky and non-risky. Here risk is understood to be an uncertainty that can cause loss (e.g., of wealth). The most typical representatives of such assets are the basic securities: stocks S and bonds (bank accounts) B. These securities constitute the basis of a financial market that can be understood as a space of assets equipped with a structure for their trading.
