Pencils of lines in generalized Laguerre spaces
Combinatorics Multidimensional Laguerre spaces subspaces pencils Grassmann spaces
2012/4/17
In the paper we characterize subspaces and pencils of lines of generalized (and multidimensional) Laguerre spaces and we consider definability of the structure of "conic" pencils in the Grassmann spac...
Pencils on real curves

2011/9/20
Abstract: We consider coverings of real algebraic curves to real rational algebraic curves. We show the existence of such coverings having prescribed topological degree on the real locus. From those e...
Exact Poisson pencils, $\tau$-structures and topological hierarchies
Dubrovin-Zhang’s perturbative integrable evolutionary PDEs
2011/7/5
We discuss, in the framework of Dubrovin-Zhang’s perturbative approach
to integrable evolutionary PDEs in 1+1 dimensions, the role of a special class
of Poisson pencils, called exact Poisson pencils...
Pencils of cubics with eight base points lying in convex position in $\mathbb{R}P^2$
Pencils of cubics eight base points convex position
2011/1/21
To a generic con guration of eight points in convex position in the plane, we associate a list consisting of the following information: for all of the 56 conics determined by ve of the points, we spe...
Spectral Problems for Operator Pencils in Non-Separated Root Zones
Operator pencils eigenvalues variational principles
2010/2/26
Variational principles for real eigenvalues of self-adjoint operator pencils in non-separated root zones are studied.
New moduli spaces of pointed curves and pencils of flat connections
New moduli spaces pointed curves pencils flat connections
2010/10/29
It is well known that formal solutions to the Associativity Equations are the same as cyclic algebras over the homology operad $(H_*(\bar{M}_{0,n+1}))$ of the moduli spaces of $n$--pointed stable cur...
On the Theory of a Certain Class of Quadratic Pencils of Matrices and Its Applications
Quadratic pencils eigenvalues eigenvectors
2010/3/5
This paper is devoted to the study of the properties of eigenvalues and eigenvectors of quadratic pencil l2C - lR - J , where C is a positive diagonal matrix, R is an arbitrary real diagonal matrix, J...
