Almost half a century ago, Yang and Mills introduced aremarkable new framework to describe elementary particles using structures thatalso occur in geometry. Quantum Yang-Mills theory is now the foundation of mostof elementary particle theory, and its predictions have been tested at manyexperimental laboratories, but its mathematical foundation is still unclear.The successful use of Yang-Mills theory to describe the strong interactions ofelementary particles depends on a subtle quantum mechanical property called the"mass gap": the quantum particles have positive masses, even thoughthe classical waves travel at the speed of light. This property has beendiscovered by physicists from experiment and confirmed by computer simulations,but it still has not been understood from a theoretical point of view. Progressin establishing the existence of the Yang-Mills theory and a mass gap and willrequire the introduction of fundamental new ideas both in physics and inmathematics.</span></p><p><span style="font-size:20px;font-family:'times new roman';">This problem is: Unsolved</span></p> <br /><br /> <label style="font-size:13px;
