Mathematics Final Year Topic: Positive Definiteness and Semidefiniteness in Parameterised Quadratic Forms

This Mathematics final year project classifies a bounded family of real quadratic forms using stated matrix criteria.

Generate the Complete Project Read project brief

Why choose this project topic?

A focused study of quadratic-form tests gives you a specific question in linear algebra and optimisation. It classifies a bounded family of real quadratic forms using stated matrix criteria. The bounded comparison creates room to explain how your evidence supports an interpretation and where the method has limits.

How do eigenvalues and applicable principal-minor conditions classify selected parameterised quadratic forms?

Agree the apparatus or dataset, comparison range and feasible measurement schedule for quadratic-form tests with your supervisor.

Proposed project objectives

  1. 01Define the materials, variables and comparison conditions for quadratic-form tests.
  2. 02Write each form as a symmetric matrix and state the correct criterion for each definiteness class.
  3. 03Evaluate the measurements or model outputs in relation to this question: How do eigenvalues and applicable principal-minor conditions classify selected parameterised quadratic forms?

A suggested research approach

Write each form as a symmetric matrix and state the correct criterion for each definiteness class. Derive parameter regions, check boundary cases and use direct vector examples to confirm indefinite behaviour where needed. Agree the available resources and record uncertainty, deviations from the protocol and any observations that challenge the initial interpretation.

What you will need

  • A bounded parameterised symmetric-matrix family
  • References on quadratic forms and definiteness criteria
  • Exact determinant, eigenvalue and boundary calculations

Keep your project scope clear

A criterion for strict positive definiteness must not be applied unchanged to positive semidefiniteness.
