The logarithmic Quot space
We introduce the logarithmic Quot space which generalises the Quot schemes of a variety X to the geometry of a pair (X,D) with D a simple normal crossing divisor on X. Such logarithmic Quot spaces interact well with degeneration and gluing formulae. We prove that the logarithmic Quot space is a …

A logarithmic cost-duration analysis
… between them. In this paper, we introduce a logarithmic cost-duration function to design an optimal trade-off between indirect and direct costs. By employing this function, we show that the optimal project duration does not depend on the network configurations. However, total cost does depend …

Logarithmic Gromov-Witten theory and double ramification cycles
… research papers, whose main topics concern the logarithmic enumerative geometry of toric varieties and its interactions with the moduli space of curves. In the first paper (joint work with Dhruv Ranganathan), we prove that the logarithmic Gromov-Witten cycles of a toric variety endowed with its …

Geometry of logarithmic mapping spaces in genus one
… the geometry of the moduli spaces of genus one logarithmic stable maps. In Chapter 2, we exhibit a smooth compactification of the moduli space of elliptic curves in a product of projective spaces with tangency along a subset of its toric boundary divisors. This is a Vakil–Zinger type of …

Derivative pricing and logarithmic portfolio optimization in incomplete markets
… and the problem of portfolio optimization for logarithmic utility. <br>In an incomplete market the no arbitrage criterion does not suffice to value contingent claims any more. Each equivalent martingale measure yields a possible price. Therefore additional criteria have to be imposed for …

EVALUATION OF THE LOGARITHMIC SPIRAL SEARCH PATTERN FOR ANTISUBMARINE WARFARE
… a recently lost target submarine using the logarithmic spiral search pattern. The study was done by developing a stochastic, time-step simulation to data farm quantitative information. The measures of effectiveness are time to regain contact, distance away from contact on regain, and overall …

A Wait-free Queue with Poly-logarithmic Worst-case Step Complexity
In this work, we introduce a novel linearizable wait-free queue implementation. Linearizability and lock-freedom are standard requirements for designing shared data structures. To the best of our knowledge, all of the existing linearizable lock-free queues in the literature have a common problem in …

Gromov Witten Invariants of Blow Ups of P² using Logarithmic Geometry
… of blow ups of P² can be derived using logarithmic Gromov-Witten theory and punctured maps. We extend the recursion to compute Gromov-Witten invariants with Hodge class insertions.

Control of the buffer and logarithmic layers in wall-bounded turbulent flows
… effect of controlling separately the buffer and logarithmic layers in wall-bounded turbulent flows. In the case of buffer-layer control, we examine the effect on near-wall turbulence of displacing the apparent, virtual origins perceived by different components of the overlying flow. This …

Probing the cosmological dynamics of a logarithmic f (R) theory of gravity
In this thesis we make a contribution in the area of Extended Theories of Gravity (ETG) by studying the dynamics of the R ln R model. We draw attention to the importance of introducing complete alternative theories of gravity and studying the possible geometrical origin of Dark Energy (unknown form …

Investigation of a more optimum trajectory than the logarithmic spiral in solar sailing
A logarithmic spiral trajectory is not the optimum trajectory for a solar sailing space vehicle. Investigation of the governing equations showed that the performance of the solar sail depends on one parameter "a". This parameter "a", defined simply as the ratio of radial to tangential forces, was …

Analysis and Modelling of Financial Logarithmic Return Data using Multifractal and Agent-Based Techniques
In recent years physicists have become involved in studying the financial market and the vast data it generates. The constantly-updated streams of information are a perfect testing ground for the hypothesis that the laws of statistical physics might apply to human behaviour. In this thesis, I study …

Towards a material damage model using the logarithmic strain, with von Mises plasticity considerations
Damage is briefly defined as the presence and growth of micro-defects in a material. This study serves to describe the computational implementation of the material damage theory adopted for ductile materials. Thus, pays attention to the computational analysis of the physical behaviour of materials …
