D-Branes and Vanishing Cycles in Higher Dimensions [article]

Mark Raugas
2001 arXiv   pre-print
Examining the cases of the sextic and heptic hypersurface Calabi-Yau varieties, as well as one example in weighted projective space, we find expressions for periods which vanish at the singular point analogous  ...  As in the known three-dimensional cases, it is the top dimensional cycle which attains zero quantum volume, even though lower dimensional cycles remain non-degenerate, indicating this phenomena to be a  ...  This is useful, as D-Branes who wrap 2j dimensional cycles on X will be mirror to d-dimensional branes on Y which have periods with leading log j z behavior near z = 0.  ...

A focus is on the higher-dimensional analogs of rational curves and surfaces, or varieties that contain a lot of rational curves.  ...  The idea here is that these varieties should be the right higher-dimensional analogs of rational curves and rational surfaces.  ... 

Passive and active metamaterial constructs and their impact on electrically small radiating and scattering systems

Richard W. Ziolkowski
2011 2011 XXXth URSI General Assembly and Scientific Symposium  
Many of these attributes have led to the consideration of engineering metamaterials and metamaterial-inspired structures for a variety of applications.  ...  These include, for example, flat lens, which depend on negative refraction effects; cloaking devices, which depend on epsilon or mu near-zero properties; artificial magnetic conductors, which depend on  ...  near-infinity properties (i.e., high impedance surfaces); and electrically small resonators and waveguides, which depend on the presence of both positive and negative MTM properties.  ...

Higher discriminants and the topology of algebraic maps [article]

Luca Migliorini, Vivek Shende
2016 arXiv   pre-print
We show that the way in which Betti cohomology varies in a proper family of complex algebraic varieties is controlled by certain "higher discriminants" in the base.  ...  (2) any component of the characteristic cycle of the proper pushforward of the constant function is a conormal variety to a component of a higher discriminant.  ...  For a weight filtration W on a complex of vector spaces V • , we write the weight polynomial w(V • ) := i,j t i (−1) i+j dim Gr i W H j (V • ). For a variety Z, we abbreviate w(Z) for w(H * c (Z)).  ...
