WebConical intersections (CIs) are diabolical points in the potential energy surfaces generally caused by point-wise degeneracy of different electronic states, and give rise to the geometric phases (GPs) of molecular wave functions. Here we theoretically propose and demonstrate that the transient redistribution of ultrafast electronic coherence in … WebTools. In algebraic geometry, a functor represented by a scheme X is a set-valued contravariant functor on the category of schemes such that the value of the functor at each scheme S is (up to natural bijections) the set of all morphisms . The scheme X is then said to represent the functor and that classify geometric objects over S given by F. [1]

WebSep 30, 2024 · Due to obvious differences in the properties of the filling body and surrounding rock, deformation always develops near the contact zone. Thus, determining the damage and failure characteristics of the contact zone between the backfill and surrounding rock is a precondition for safe production in mines. Taking Jinchuan mine as … WebIn classical algebraic geometry, a generic point of an affine or projective algebraic variety of dimension d is a point such that the field generated by its coordinates has transcendence degree d over the field generated by the coefficients of the equations of the variety. In scheme theory, the spectrum of an integral domain has a unique ... WebSimilarly, if you are happy about thinking of points of Y as being morphisms from Specs of fields then the fibre at a point x: S p e c k → Y is the fibre product S p e c k × Y X, often denoted X x or X ⊗ Y k. Now, if you are working with varieties (or schemes of locally of finite type) over the complex numbers (or an algebraically closed ... tia cheer
