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...

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...
Abstract: In this paper with study some properties of bi-Hamiltonian deformations of Poisson pencils of hydrodynamic type. More specifically, we are interested in determining those structures of the f...
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...

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...
Variational principles for real eigenvalues of self-adjoint operator pencils in non-separated root zones are studied.
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...
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...
