Researchers are exploring advanced mathematical problems involving integral regularization, Green's functions, and Diophantine equations. A key focus is the regularization of a contour integral, employing complex analysis techniques. This involves evaluating an integral using the residue theorem and considering the behavior of the integral along a semi-circular path as its radius approaches infinity. The aim is to understand the mathematical structures and obtain accurate results when dealing with divergent integrals.

Another area of study involves the asymptotics of Green's functions near the diagonal on a compact Riemannian manifold. A complex mathematical statement has been presented regarding the behavior of these functions, specifically that it involves a logarithmic term that appears only to the first power. Researchers are looking for a formal proof for the behavior of these Green's functions, as well as deeper connections between these functions and the geometry of the manifold itself. Finally, mathematicians are investigating an unsolved Diophantine equation which attempts to determine solutions for the equation \(10(x^7+y^7+z^7)=7(x^2+y^2+z^2)(x^5+y^5+z^5)\) where x,y, and z are relative integers and \(x+y+z≠0 \). It has been proven that if a solution exists, x + y + z is divisible by 7, and currently various methods are being employed in order to see if a contradiction can be found which would prove that this equation has no solutions.
