	STUDIA MATHEMATICA - Issue no. 4 / 2013

	Article:	PRIMES OF THE FORM +- a² +- qb². Authors: .


	Abstract: Representations of primes by simple quadratic forms, such as ±a²±qb², is a subject that goes back to Fermat, Lagrange, Legendre, Euler, Gauss and many others. We are interested in a comprehensive list of such results, for q ≤ 20. Some of the results can be established with elementary methods and we exemplify that in some instances. We are introducing new relationships between various representations. Mathematics Subject Classification (2010): 11E25, 11A41, 11A67. Keywords: Quadratic reciprocity, Pigeonhole principle.
