Context. RR Gem is one of the few Blazhko RR Lyrae that has photometric observations available extended enough to study the long-term courses of its pulsation and modulation properties in detail. Aims. We investigate the pulsation and modulation properties and the relations between them in RR Gem using photometric observations from the past 70 years in order to gain further insight into the nature of the Blazhko modulation. Methods. We studied the photographic, photoelectric, and CCD light curves obtained at the Konkoly Observatory and other authors' published maxima observations. Detailed analysis of the light curves, maximum brightness, and O-C data are carried out. Results. RR Gem showed modulation most of the time it was observed. The modulation amplitude showed strong variations from the undetectable level (less than 0.04 mag in maximum brightness) to about 0.20 mag. The amplitudes of the amplitude and phase modulations showed parallel changes, thus the total "power" of the modulation have changed during the past 70 years. Parallel changes in the pulsation and modulation periods occur with a dP mod /dP puls = 1.6 ± 0.8 × 10 3 ratio. We also detected 0.05−0.1 mag changes in the mean maximum brightness and mean pulsation amplitude.

We show that for smooth complex projective varieties the most general combinations of Chern numbers that are invariant under the Kequivalence relation consist of the complex elliptic genera.

Another one is Totaro's work [16]: complex elliptic genera = complex cobordism ring modulo classical flops, or equivalently Chern numbers invariant under classical flops consist of precisely the complex elliptic genera.We show in this paper a generalization of Totaro's result: complex elliptic genera = complex cobordism ring modulo K-equivalence. A surprising conclusion is that in the complex cobordism ring, the ideal generated by classical flops equals the seemingly much larger ideal generated by all K-equivalent pairs. To summarize our approach, we follow the meta theorem. The target invariants are genera (or Chern numbers), which by definition are certain integrals, so we only need a nice change of variable formula. This is treated in two steps:Inspired by the work of Hirzebruch et. al.[8] on the characterization of the (real) elliptic genera (of Landweber and Stong) as the most general genera that are multiplicative on fiber bundles with fiber P 2n−1 for all n ∈ N, we characterize the complex elliptic genera (studied by Witten, Hirzebruch and subsequently by Krichever, Höhn and Totaro) in a similar flavor via blowingups along smooth centers.Let X be a compact complex manifold or a proper smooth variety (over an algebraically closed field of arbitrary characteristic). For a commutative ring R, an R-genus ϕ is defined by a power series Q(x) ∈ R [[x]] through Hirzebruch's multiplicative sequence K Q (or K ϕ ). As usual we write Q(x) = x/f (x).Theorem A (residue theorem). For any cycle D in X and for any blowing-up φ : Y → X along smooth center Z with exceptional divisor E, one has for any power seriesHere n i 's denote the formal Chern roots of the normal bundle N Z/X and the residue stands for the coefficient of the degree −1 term of a Laurent power series with coefficients in the cohomology ring or the Chow ring of X.Theorem B (characterization of complex elliptic genera). Consider the following sets of power series f (x) = x + · · · ∈ C[[x]] (or C-genera φ's): S 1 : ϕ admits a first step change of variable formula. That is, for each r ∈ N there exists a power series A(t, r) in t that serves as the Jacobian Licensed to Yale Univ. Prepared on Thu Jul 2 05:05:02 EDT 2015 for download from IP 130.132.123.28.
