Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / O objetivo deste trabalho à estudar o comportamento da regularidade de Castelnuovo- Mumford em arranjos de subespaÃos lineares no espaÃo projetivo, para isto, nos norteamos pelo artigo de tÃtulo "Uma limitaÃÃo sharp para a regularidade de Castelnuovo-Mumford de arranjos de subespaÃos" dos autores Harm Derksen e Jessica Sidman. Em um primeiro momento, daremos algumas noÃÃes preliminares e apresentaremos resultados auxiliares. Num segundo momento, definiremos os principais objetos deste trabalho, demonstraremos os resultados principais e daremos um exemplo que mostra que a limitaÃÃo encontrada à a melhor possÃvel. / The objetive of this work is study the behavior of the Castelnuovo-Mumford regularity in arrangements of linear subspaces in projetive spaces, for this, we use Jessica Sidman and Harm Derksen article of title "A sharp bound for the Castelnuovo-Mumford regularity of subspace arrengements". At first, we give some preliminary notions and present auxiliary results. In a second moment, we define the main objects of this work proof the main results and give a example which show that the bound is sharp.

In the first chapter “Impact of Quantitative Easing at the Zero Lower Bound (with J. Dorich, R. Mendes)”, we introduce imperfect asset substitution and segmented asset markets, along the lines of Andres et al. (2004), in an otherwise standard small open-economy model with nominal rigidities. We estimate the model using Canadian data. We use the model to provide a quantitative assessment of the macroeconomic impact of quantitative easing (QE) when the policy rate is at its effective lower bound. In the second chapter “Impact of Forward Guidance at the Zero Lower Bound”, I consider alternative monetary policy rules under commitment in a calibrated three-equation New Keynesian model and examine the extent to which forward guidance helps to mitigate the negative real impact of the zero lower bound. The simulation results suggest that the conditional statement policy prolongs the zero lower bound duration for an additional 4 quarters and reverses half of the decline in inflation associated with the lower bound. It even generates a period of overshooting in inflation three quarters after the initial negative demand shock. Alternatively, the effect of price-level targeting as a forward guidance policy at the zero lower bound is slightly different. In the third chapter “Impact of Quantitative Easing on Household Deleveraging”, I extend the DSGE model in the first chapter with some financial frictions to explore the effects of QE on asset prices and household balance sheet. There are two effects of QE on aggregate output originated from the model. First, QE leads to a decline in term premium, which increases current consumption relative to future consumption. Second, it leads to a lower loan to collateral value ratio and a decline in external finance premium. Favorable financing condition encourages further accumulation of household debt at cheaper rates, in turn, leads to an immediate higher household debt to income ratio. In the consideration of the future withdrawal of any stimulus provided from QE, this would pose greater challenges as it implies much intensive household deleveraging process. I provide some sensitivity analysis around key parameters of the model.

Effects of binding on the electromagnetic structure of a nucleon in a nucleus is examined for the two-pion part of the nucleon form factor. The nucleon is assumed to be bound in a harmonic oscillator potential and also coupled to the pion field through the Chew-Low type interaction. In the tight-binding limit, the nucleon structure approaches that given in the static Chew-Low theory, as expected, while the loose-binding limit gives the free nucleon case with nucleon recoil corrections. Implications of this binding on the magnetic moments of the tri-nucleon systems are investigated, and it is found that for a realistic strength of the harmonic oscillator potential the binding effect is too small to be very significant. Effects of the Pauli Principle are also discussed. / Thesis / Master of Science (MSc)
