Multiloop algebras, iterated loop algebras and extended affine Lie algebras of nullity 2 [PDF]
Let M(n) be the class of all multiloop algebras of finite dimensional simple Lie algebras relative to n-tuples of commuting finite order automorphisms.

Submanifolds with nonparallel first normal bundle revisited [PDF]
In this paper, we analyze the geometric structure of an Euclidean submanifold whose osculating spaces form a nonconstant family of proper subspaces of the same dimension.

Contact co-isotropic CR submanifolds of a pseudo-Sasakian manifold
It is proved that any co-isotropic submanifold M of a pseudo-Sasakian manifold M˜(U,ξ,η˜,g˜) is a CR submanifold (such submanfolds are called CICR submanifolds) with involutive vertical distribution ν1.

A marginally trapped surface in a spacetime is a Riemannian surface whose mean curvature vector is lightlike at every point. In this paper we give an up-to-date overview of the differential geometric study of these surfaces in Minkowski, de Sitter, anti ...

The homology of path spaces and Floer homology with conormal boundary conditions [PDF]
We define the Floer complex for Hamiltonian orbits on the cotangent bundle of a compact manifold satisfying non-local conormal boundary conditions. We prove that the homology of this chain complex is isomorphic to the singular homology of the natural ...

Stability of Relative Equilibria in the Planar N-Vortex Problem [PDF]
We study the linear and nonlinear stability of relative equilibria in the planar N-vortex problem, adapting the approach of Moeckel from the corresponding problem in celestial mechanics.

Nonnegatively curved Euclidean submanifolds in codimension two
We provide a classification of compact Euclidean submanifolds $M^n\subset{\mathbb{R}}^{n+2}$ with nonnegative sectional curvature, for $n\ge 3$. The classification is in terms of the induced metric (including the diffeomorphism classification of the ...

Background and Aim: Boredom is a psychological phenomenon which is caused by many factors and it can be accompanied by undesirable effects such as reduction of professional performance. Boredom in the workplace leads to a decrease in job satisfaction and
