The PVCC Center for the Performing Arts, containing stage facilities for drama and music performances, opened in 2005. In 2007 the L-Building was built to house classes for Nursing, Fire Science and EMT. The building was built using a modular construction system. [4] In 2007 PVCC acquired the adjacent George L. Campbell Branch Library.
The college began offering classes there in the fall of 2012. PVCC also opened a center in downtown Charlottesville, Virginia, in January 2013. PVCC is housed on the ground floor in the historic Jefferson School building. The college offers day and evening classes at this facility and has introduced a new associate degree program in culinary ...
PVCC may refer to: Paradise Valley Community College, a public community college in Phoenix, Arizona; Piedmont Virginia Community College, a public community college ...
The class number of a number field is by definition the order of the ideal class group of its ring of integers. Thus, a number field has class number 1 if and only if its ring of integers is a principal ideal domain (and thus a unique factorization domain). The fundamental theorem of arithmetic says that Q has class number 1.

That is because what enters the analytic formula for the class number is not h, the class number, on its own — but h log ε, where ε is a fundamental unit. This extra factor is hard to control. It may well be the case that class number 1 for real quadratic fields occurs infinitely often.
In mathematics, class number may refer to Class number (group theory), in group theory, is the number of conjugacy classes of a group; Class number (number theory), the size of the ideal class group of a number ring; Class number (binary quadratic forms), the number of equivalence classes of binary quadratic forms of a given discriminant
The idea of the proof of the class number formula is most easily seen when K = Q(i).In this case, the ring of integers in K is the Gaussian integers.. An elementary manipulation shows that the residue of the Dedekind zeta function at s = 1 is the average of the coefficients of the Dirichlet series representation of the Dedekind zeta function.
