.bg .bg The domain name .bg is the country code top-level domain (ccTLD) in the Domain Name System of the Internet for Bulgaria. It is currently operated by Register.BG. The domain name registration guideline impose the following restrictions: Domains can be registered by companies or citizens of the European Union, or foreign companies that have registered branches or commercial representatives in Bulgaria. The price of domain registration is 30 euro per year (36 € including VAT). Until mid-2006, the price was US$50 for one-time registration plus $50 per year (total of $120 including VAT for the first year). For local standards
AF+BG theorem the greatest common divisor of "f" and "g". The AF+BG condition expresses, in terms of divisors (sets of points, with multiplicities), a similar condition under which a homogeneous polynomial "H" in three variables can be written as an element of the ideal generated by two other polynomials "F" and "G". This theorem is also a refinement, for this particular case, of Hilbert's Nullstellensatz, which provides a condition expressing that some power of a polynomial "h" (in any number of variables) belongs to the ideal generated by a finite set of polynomials.
