Connected non-complete signed graphs which have symmetric spectrum but are not sign-symmetric
Examples and Counterexamples, 2021 A signed graph Ġis called sign-symmetric if it is switching isomorphic to its negation −Ġ, where −Ġis obtained by reversing the sign of every edge of Ġ. The authors of Belardo et al.

OPEN STRING ON SYMMETRIC PRODUCT [PDF]
International Journal of Modern Physics A, 2001 We discuss some basic properties of the open string on the symmetric product which is supposed to describe the open string field theory in discrete light-cone quantization (DLCQ). We first derive the consistent twisted boundary conditions for Annulus/Möbius/Klein Bottle diagrams and give the explicit form of the corresponding amplitude.

Discrepancy of Symmetric Products of Hypergraphs [PDF]
The Electronic Journal of Combinatorics, 2006 For a hypergraph ${\cal H} = (V,{\cal E})$, its $d$–fold symmetric product is defined to be $\Delta^d {\cal H} = (V^d,\{E^d |E \in {\cal E}\})$. We give several upper and lower bounds for the $c$-color discrepancy of such products. In particular, we show that the bound ${\rm disc}(\Delta^d {\cal H},2) \le {\rm disc}({\cal H},2)$ proven for all $d$ in ...

Elementary evolutions in Banach algebra [PDF]
, 2013 An elementary class of evolutions in unital Banach algebras is obtained by integrating product functions over Guichardet's symmetric measure space on the half-line.

The symplectic geometry of higher Auslander algebras: Symmetric products of disks
Forum of Mathematics, Sigma, 2021 We show that the perfect derived categories of Iyama’s d-dimensional Auslander algebras of type ${\mathbb {A}}$ are equivalent to the partially wrapped Fukaya categories of the d-fold symmetric product of the $2$-dimensional unit disk with finitely many ...

Divisor Varieties of Symmetric Products [PDF]
International Mathematics Research Notices, 2021 Abstract The geometry of divisors on algebraic curves has been studied extensively over the years. The foundational results of this Brill-Noether theory imply that on a general curve, the spaces parametrizing linear series (of fixed degree and dimension) are smooth, irreducible projective varieties of known dimension.

The bisymplectomorphism group of a bounded symmetric domain [PDF]
, 2008 In a previous paper with A. Loi we introduced the so called symplectic duality between Hermitian symmetric spaces. Such duality consists in a bysimplectomorphism between an open and dense subset of a compact Hermitian symmetric space and its non-compact ...
