In this note we obtain a new convergence result for the Adomian decomposition method.

In this note, we present a simple non-directed graph proof of Sharkovsky's theorem which is different from the one given in [2].

Almost uniform version of noncommutative Wiener-Wintner ergodic theorem and its extension to Besicovitch weights are proved.

We give a cohomological characterization of Gromov relative hyperbolicity. As an application we prove a converse to the combination theorem for graphs of relatively hyperbolic groups given in a previous paper of the first author. We build…

There are proven few analogues of the Theorem of Moser using The Approximation Theorem of Artin.

We give a detailed exposition of the homotopy theory of equivalence relations, perhaps the simplest nontrivial example of a model structure.

Relative trace formulas play a central role in studying automorphic forms. In this paper, we use a relative trace formula approach to derive a Kuznetsov type formula for the group $GSp_4$. We focus on giving a final formula that is as…

We give lower bounds on the case of worst inhomogeneous approximation.

In this note we give a detailed proof of a theorem of Aubin.

A proof is given of Rosenthal's \(\ell_1\) theorem.

In this note, we give a probabilistic interpretation of the Central Limit Theorem used for approximating isotropic Gaussians in [1].

A complete p-adic Khintchine type theorem for approximation by p-adic algebraic numbers is established.

We present a necessary and sufficient condition for the topological equivalence of a continuous function on a plane to a projection onto one of coordinates.

We prove some new results related to Tanaka's formula.

We propose to interpret Levinson's theorem as an index theorem. This exhibits its topological nature. It furthermore leads to a more coherent explanation of the corrections due to resonances at thresholds.

We survey classical and recent results on exponents of Diophantine approximation. We give only a few proofs and highlight several open problems.

We prove a combination theorem for PD(n)-pairs.

We give a homological characterisation of relatively prosolvable projective groups.

We attempt to prove the Razumov-Stroganov conjecture using a bijectional approach. We have been unsuccessful but we believe the techniques we present can be used to prove the conjecture.

This, and its sequel, concern some variations of a classical theorem of A.D. Alexandrov and teh Hopf Lemma.
