This paper considers an undirected polymer chain on Zd, d⩾2, with i.i.d. random charges attached to its constituent monomers. Each self-intersection of the polymer chain contributes an energy to the interaction Hamiltonian that is equal to the product of the charges of the two monomers that meet. The joint probability distribution for the polymer chain and the charges is given by the Gibbs distribution associated with the interaction Hamiltonian. The object of interest is the annealed free… 

Scaling limits for the random walk penalized by its range in dimension one

In this article we study a one dimensional model for a polymer in a poor sol-vent: the random walk on Z penalized by its range. More precisely, we consider a Gibbs transformation of the law of the

Path properties of levy processes

This thesis can be split into two main components, the �first of which looks at the fractal dimension, specifically, box-counting dimension, of sets related to subordinators (non-decreasing L�evy

Transience and Recurrence of Markov Processes with Constrained Local Time

We study Markov processes conditioned so that their local time must grow slower than a prescribed function. Building upon recent work on Brownian motion with constrained local time in [5] and [33],

Annealed Scaling for a Charged Polymer

This paper studies an undirected polymer chain living on the one-dimensional integer lattice and carrying i.i.d. random charges. Each self-intersection of the polymer chain contributes to the

Multidimensional Random Polymers: A Renewal Approach

In these lecture notes we discuss ballistic phase of quenched and annealed stretched polymers in random environment on \(\mathbb{Z}^{d}\) with an emphasis on the natural renormalized renewal

Random Walk Intersections: Large Deviations and Related Topics

The material covered in this book involves important and non-trivial results in contemporary probability theory motivated by polymer models, as well as other topics of importance in physics and

Long-time tails in the parabolic Anderson model

We consider the parabolic Anderson problem ∂ t u = κΔu + ξu on (0, ∞) × Z d with random i.i.d. potential ξ = (ξ(z)) z ∈ Zd and the initial condition u(0,.) ≡ 1. Our main assumption is that esssup

JOINT DENSITY FOR THE LOCAL TIMES OF CONTINUOUS-TIME MARKOV CHAINS: EXTENDED VERSION

We investigate the local times of a continuous-time Markov chain on an arbitrary discrete state space. For fixed finite range of the Markov chain, we derive an explicit formula for the joint density

A large-deviation result for the range of random walk and for the Wiener sausage

Abstract. Let {Sn} be a random walk on ℤd and let Rn be the number of different points among 0, S1,…, Sn−1. We prove here that if d≥ 2, then ψ(x) := limn→∞(−:1/n) logP{Rn≥nx} exists for x≥ 0 and

An invariance principle for random walk bridges conditioned to stay positive

We prove an invariance principle for the bridge of a random walk conditioned to stay positive, when the random walk is in the domain of attraction of a stable law, both in the discrete and in the

On the Equivalence of Euler-Lagrange and Noether Equations

We prove that, under the condition of nontriviality, the Euler-Lagrange and Noether equations are equivalent for a general class of scalar variational problems. Examples are position independent
