(2009-06-17)Mixed valence manganites with the perovskite structure R1-xAxMnO3 (where R = La, Nd, Pr and A = Ba, Ca, Sr, Pb) have been a popular subject of contemporary research because of their interesting physical properties such as ... -
Grushin Multipliers and Toeplitz Operators
This work investigates advanced concepts in functional analysis and partial differential equations, focusing on Sobolev spaces and their weighted variants. The study explores properties of functions in Lp(Rn+1)L^p(\mathb ... -
Hand-Movement Prediction Using LFP Data
(2011-08-08)The last decade has seen a surge in the development of Brain-Machine Interfaces (BMI) as assistive neural devices for paralysis patients. Current BMI research typically involves a subject performing movements by controlling ... -
Hardy's inequalities for Grushin operator and Hermite multipliers on Modulation spaces
This thesis consists of two broad themes. First one revolves around the Hardy's inequalities for the fractional power of Grushin operator $\G$ which is chased via two different approaches. In the first approach, we first ... -
Harmonic Map Heat Flow and Framed Surface-group Representations
This thesis concerns the construction of harmonic maps from certain non-compact surfaces into hyperbolic 3-space H3 with prescribed asymptotic behavior and has two parts. The focus of the first part is when the domain ... -
Heavy flavour and direct photon probes of the gluon Sivers function
Traditionally the production of heavy quarkonia, heavy-flavour mesons as well as of direct photons, has been used to constrain the gluon density inside the proton. In this thesis, I have assessed various heavy flavour ... -
Herglotz representation, approximation by inner functions, and Hankel operators
This thesis can be broadly categorized under the theories of multi-variable operators and holomorphic functions, structured into two distinct parts. The first part investigates the relationship between two classical theorems: ... -
Hermitian Metrics and Singular Riemann Surface Foliations
The main aim of this thesis is to understand curvature properties of a given hermitian metric by restricting it to the leaves of a suitable singular Riemann surface foliation. We will specifically consider the complete ...
