Summary on Grant Application Form 
The proposed research is in Pure Mathematics, more precisely, in an area of intersection of Algebraic Number Theory and Representation Theory. One of the main goals of the first subject is to solve Diophantine problems that ask for whole number solutions to polynomial equations in several variables. A very famous example of such a Diophantine problem is due to the French mathematician Fermat, and asks whether it is possible for the sum of two integer nth powers to be again the nth power of an integer. When the parameter n is equal to two, it has been known since ancient times that there are infinitely many solutions to this problem, such as 9 + 16 = 25 and 25 + 144 = 169. Fermat guessed way back in the seventeenth century that his problem has no interesting solutions whatsoever for any higher value of n, but a rigorous proof of this guess, the socalled Fermat's Last Theorem, was only obtained around 20 years ago by the British mathematician Andrew Wiles. The second subject, Representation Theory, tries to determine all the possible ways in which symmetries can occur in nature, and has numerous applications in several neighbouring academic disciplines such as Crystallography and Theoretical Physics. A typical problem in Representation Theory asks for the classification of the basic building blocks, or atoms, of the theory  known as the irreducible representations. To mention an example: according to the Standard Model of Theoretical Physics, nearly everything around us in the visible universe is composed of certain elementary particles called Quarks. The classification and behaviour of these quarks is in turn explained by the classification and behaviour of the irreducible representations of the threedimensional special unitary group SU(3). The proposed research will develop new geometric tools and methods in order to classify the irreducible representations in a particular subfield of Representation Theory. This classification project would then be used to build a conceptual bridge called the padic local Langlands correspondence between Algebraic Number Theory and Representation Theory, which would in turn be used to make progress in both areas by transferring information from one to the other.
