Proof triangle inequality absolute value
WebTheorem 2.1. An absolute value · on a field F is non-archimedean if and only if it satisfies the non-archimedean triangle inequality. In particular, any absolute value on a field with positive characteristic must satisfy the non-archimedean triangle inequality. Proof. The sufficiency has already been noted, so the only issue is necessity. WebAbsolute Values and the Triangle Inequality De nition.

WebThe Cauchy-Schwarz Inequality holds for any inner Product, so the triangle inequality holds irrespective of how you define the norm of the vector to be, i.e., the way you define scalar product in that vector space. In this case, … Webthe absolute value of the dot product is bounded by the product of the lengths of the vectors: v ·w ≤ kvkkwk. This is the simplest form of the general Cauchy–Schwarz inequality. We present a simple, algebraic proof that does not rely on the geometrical notions of length and angle and thus demonstrates its universal validity for any inner ...
