Derived Categories of Quadric Fibrations and Intersections of Quadrics

We construct a semiorthogonal decomposition of the derived category of coherent sheaves on a quadric fibration consisting of several copies of the derived category of the base of the fibration and the derived category of coherent sheaves of modules over the sheaf of even parts of the Clifford algebras on the base corresponding to this quadric fibration generalizing the Kapranov’s description of...

Spaces of Sections of Quadric Surface Fibrations over Curves

Let k be a field of characteristic not equal to two, B a smooth projective curve of genus g(B) over k, and F its function field. A quadric hypersurface fibration is a flat projective morphism π : X → B such that each geometric fiber is a quadric hypersurface with at worst an isolated singularity and the generic fiber is smooth. Sections σ : B → X of π are in bijection with rational points X(F )...

Corrigendum to "On multiplication (m, n)-hypermodules" [European J. Combin. 44(2015) 153-171]

1. In Definition 2.4, ‘‘(iv) {0} = g(r i−1 1 , 0, r n−1 i+1 , x)’’. 2. In Definition 2.5, ‘‘g(R(n−1),N) ∈ P (N)’’. 3. Page 5, line 1, ‘‘0 ∈ g(0, 1 R ,m) ⊆ g(R, 1 (n−2) R ,m)’’. 4. Page 6, line 4, ‘‘f (x1 ) = h(x m 1 ) = m i=1 xi = m i=1 xi =’’. 5. Page 7, Lemma 3.7 is not true (is removed) and XP(M) is not a subhypermodule ofM . Hence, we define the set XP(M) accompany with XP(M) and consider...

Corrigendum Corrigendum to “ Saturated simplicial complexes ” [ J . Combin

One of the main results in the paper of the title is potentially incorrect as stated. To correct the statement the notion of the link of a subcomplex in a simplicial complex is required, and this is more general than the usual definition of link. This new definition is given here and it is shown that it indeed gives the required theorem. The aim of the paper in the title is to provide a local c...
