Polytopes of Stochastic Tensors
Haixia Chang, Vehbi E. Paksoy, Fuzhen Zhang
Considering stochastic tensors (i.e., nonnegative hypermatrices in which every sum over one index , , or , is 1), we study the polytope ($Ω…
An inequality for tensor product of positive operators and its applications
Xaixia Chang, Vehbi E. Paksoy, Fuzhen Zhang
We present an inequality for tensor product of positive operators on Hilbert spaces by considering the tensor product of operators as words on certain alphabets (i.e., a set of let…
Angles, triangle inequalities, correlation matrices and metric-preserving and subadditive functions
Diego Castano, Vehbi E. Paksoy, Fuzhen Zhang
We study the triangle inequalities for angles (with different definitions) and present inequalities concerning the entries of correlation matrices through the positivity of $3\time…
Effective cone of for odd
Vehbi Emrah Paksoy
In this work, we compute the effective cone of the space of pointed genus 0 rational curves, for odd . We will, in fact, use the equivalence of $\bar{M}_{0,n…
On the cohomology of spatial polygons in Euclidean spaces
Vehbi Emrah Paksoy
We compute the cohomology of polygon spaces using their identification to (semi) stable configuration of weighted points on complex projective line. This cohomology is already give…
Mirror Principle For Flag Manifolds
Vehbi Emrah Paksoy
We obtain A- and B- series of flag manifolds for T-equivariant tangent bundles and equivariant Chern polynomial following the arguments of Lian, Liu, Yau.
