SUMMARY:A Functional Renormalization Group Study of Correlated Electrons 
DESCRIPTION:Featuring Nahom Yirga\n\nPart of the Preliminary Oral Exam.\n\n
	Examining Committee:  David Campbell\, Anders Sandvik\, Emanuel Katz\, Shya
	m Erramilli\n\nAbstract:\n\nWe use the functional renormalization group(fRG
	) scheme to study the dynamics of strongly correlated fermions on a lattice
	. The proposed approach extends the fRG to account for dynamical correction
	s to the vertex\, the renormalization of the propagator due to the self-ene
	rgy and momentum dependant interactions away from the fermi surface. Using 
	this approach we study the ground state phase diagram of Hubbard Models wit
	h bond-charge interactions and multi-orbital Hubbard models. We propose a g
	eneralized fRG scheme for any two dimensional multi-band model.  \n\n![Yirg
