Functional Analysis is a broad area of modern mathematics
that has grown out of, and maintains connections with, multiple diverse topics
in science, engineering, and technology. Our
group pursues several lines of investigation, including basic research in
pure mathematics to improve general understanding of the subject, as well
as development of mathematical results that lay the groundwork for
applications. A common theme among our group members' work is the
study of operators on Hilbert spaces, which may be though of as
infinitedimensional generalizations of Euclidean space.
Many important collections of operators have algebraic structure that can be exploited to study all the operators simultaneously. Among other benefits, this algebraic viewpoint allows for the spectral theory of a single operator to be extended to a collection, and it provides a way to generalize the study of continuous functions on a topological space to noncommutative algebras, earning the subject the name "noncommutative topology".
Wavelets may be visualized as brief wavelike oscillations that can be combined to produce more complicated waves. Decomposing signals into wavelets is useful for both analysis and transmission of the signals, and techniques from Harmonic Analysis and Fourier Analysis are often applied. As a mathematical tool, wavelets can be used to extract information from many different kinds of data, including audio signals, images, and video.
Quantum groups include several kinds of noncommutative algebras (or the spaces they act on) that arise in quantum mechanics and theoretical physics. Quantum groups are often viewed as depending on an auxiliary parameter, such as h or q. As this parameter varies, it deforms a commutative algebra of functions into an algebra of functions on a "noncommutative space" (in the spirit of the noncommutative geometry of Alain Connes).
While classical information is stored in bits of 0 or 1, quantum information is stored in "qubits" operating under two key principles of quantum physics: superposition (meaning each qubit simultaneously represents a 0 and 1 with different probabilities for each), and entanglement (meaning one qubit's state affects the state of another). Using these principles, qubits can process information in ways that are difficult or impossible with classical methods.
