چکیده
We discuss and prove a number of results for calculating characteristic cycles, or graded, enriched characteristic cycles. We concentrate particularly on results related to hypersurfaces.

Chern classes and Characteristic Cycles of Determinantal Varieties
Let K be an algebraically closed field of characteristic 0. For m ≥ n, we define τm,n,k to be the set of m× n matrices over K with kernel dimension ≥ k. This is a projective subvariety of Pmn−1, and is called the (generic) determinantal variety. In most cases τm,n,k is singular with singular locus τm,n,k+1. In this paper we give explicit formulas computing the Chern-Mather class (cM ) and the C...
متن کاملINVESTIGATION OF NON-LINEAR CYCLES’ PROPERTIES IN STRUCTURES SUBJECTED TO ENDURANCE TIME EXCITATION FUNCTIONS
Endurance Time Method (ET) is a dynamic analysis in which structures are subjected to intensifying accelerograms that are optimized in a way that seismic performance of structures can be estimated at different hazard levels with the best possible accuracy. For the currently available ET accelerograms, regardless of the shaking characteristic, an excitation level is recognized as a representativ...
متن کاملListening in to the Pascal
The work of an electronic computer in solving arithmetical problems consists in many cases of running through a succession of repeated cycles, and of cycles within cycles. This will perhaps have become clear from the foregoing articles in this number. The idea has occurred to many builders of electronie computers to listen in to these cycles by making audible through a loudspeaker the passing o...
متن کاملBuckling and vibration analysis of angle -ply symmetric laminated composite plates with fully elastic boundaries
The main focus of this paper is on efficiency analysis of two kinds of approximating functions (characteristic orthogonal polynomials and characteristic beam functions) that have been applied in the Rayleigh-Ritz method to determine the non-dimensional buckling and frequency parameters of an angle ply symmetric laminated composite plate with fully elastic boundaries. It has been observed that o...
متن کاملCharacteristic Classes of Complex Hypersurfaces
The Milnor-Hirzebruch class of a locally complete intersection X in an algebraic manifold M measures the difference between the (Poincaré dual of the) Hirzebruch class of the virtual tangent bundle of X and, respectively, the Brasselet-Schürmann-Yokura (homology) Hirzebruch class of X. In this note, we calculate the Milnor-Hirzebruch class of a globally defined algebraic hypersurface X in terms...
