The mathematical concept of norm is a measure which describes some sense of the length or size of the corresponding mathematical entity, for examples: the absolute value of a real number, the modulus of a complex number, the vector magnitude, the matrix norm, and the quaternion norm. The absolute value of a real number denoted by || where is the given real number, is if ≥0 and – if <0. Thus || is positive definite except when =0. For any two real numbers and : ||=||||, |+|≤||+||, |-|≥|||-|||, and >0,||≤ if and only if –<<. The modulus of a complex number =+ denoted by || and is simply equal to the non-negative square root of ²+². The square of the vector magnitude is given by the matrix product of the transpose vector and the vector itself: ||²=† where is defined as the column vector. The matrix norm is defined for a square matrix with real or complex elements as a non-negative number with the properties that ||>0 if ≠0 and ||=0 if =0, ||=|| for any positive scalar , |+|≤||+||, and ||≤||||. The norm of a quaternion denoted by || is the scalar defined by the square root of the sum of squares of the corresponding numerical coefficients, for example the quaternion given by =2-2+2-2, ||²=2²+(-2)²+2²+(-2)²=16 → ||=4.
For the squares of energy of the quantum vacuum fluctuations of zero-point energies, the square norm is given as the quadratic form of infinite order. For the 8th order, ( 8 )=(₁-₂+₃-₄+₅-₆+₇-₈)²= ₁² cos₁₁+₂² cos₂₂+₃² cos₃₃+₄² cos₄₄+₅² cos₅₅+₆² cos₆₆+₇² cos₇₇+₈² cos₈₈-2 ₁₂cos₁₂+2 ₁₃cos₁₃-2 ₁₄cos₁₄+2 ₁₅cos₁₅-2 ₁₆cos₁₆+2 ₁₇cos₁₇-2 ₁₈cos₁₈-2 ₂₃cos₂₃+2 ₂₄cos₂₄-2 ₂₅cos₂₅+2 ₂₆cos₂₆-2 ₂₇cos₂₇+2 ₂₈cos₂₈-2 ₃₄cos₃₄+2 ₃₅cos₃₅-2 ₃₆cos₃₆+2 ₃₇cos₃₇-2 ₃₈cos₃₈-2 ₄₅cos₄₅+2 ₄₆cos₄₆-2₄₇cos₄₇+2 ₄₈cos₄₈-2 ₅₆cos₅₆+2 ₅₇cos₅₇-2 ₅₈cos₅₈-2 ₆₇cos₆₇+2 ₆₈cos₆₈-2 ₇₈cos₇₈. It can noted that for singular symmetric Hadamard coefficient matrices and if all ’s have equal magnitudes then even order (even)=0, while (odd)>0 if there are more plus signs and (odd)<0 if there are more minus signs. Plus signs indicate excess useful energy. Minus signs indicate excess useless energy. On the other hand, changing the direction cosines can either increase or decrease useful energies and for every 3D Cartesian triple cos²₁₁+ cos²₂₂+ cos²₃₃=1. Furthermore, rationalization of distinct products such that ₁₂=₁-₂ allows additional increase or decrease of useful energy. Extension into non-symmetric nonsingular coefficient matrices becomes known as the eigenvalue problem and solution of quantum mechanics.
