SUMMARY

The notation |x,y| in mathematical analysis represents the norm or absolute value of the inner product of vectors x and y. This notation is often used interchangeably with or (x, y) in various texts. Understanding this notation is crucial for interpreting vector relationships in higher-dimensional spaces.

PREREQUISITES
  • Understanding of vector spaces
  • Familiarity with inner product definitions
  • Knowledge of norms in mathematical analysis
  • Basic concepts of linear algebra
NEXT STEPS
  • Study the properties of inner products in vector spaces
  • Learn about different types of norms, including L2 norm
  • Explore the geometric interpretation of inner products
  • Investigate applications of inner products in machine learning
USEFUL FOR

Students and professionals in mathematics, physics, and engineering who are looking to deepen their understanding of vector analysis and inner product spaces.

Without any context it's hard to tell, but it might mean the norm or absolute value of the inner product of x and y. Many texts represent the inner product as <x, y> or as (x, y).
