Pengaruh Capital Gain Dan Pembagian Dividen Terhadap Volume Perdagangan Saham Pada Perusahaan Keuangan Yang Terdaftar Di Bursa Efek Indonesia

The purpose of this study was to determine the effect of Capital Gain and Dividend Distribution on Stock Trading Volume in Financial Companies during the 2016- 2020 period, as well as to determine the effect of Capital Gain and Dividend Distribution together (simultaneously) on Stock Trading Volume in Financial Companies during the period. 2016-2020. The theoretical basis of this research consists of financial management, financial statements and ratio analysis of financial statements. Techniques Data collection is carried out using secondary data taken from the Indonesia Stock Exchange www.idx.co.id. This research analysis tool uses multiple linear regression analysis. The results of this study include 1).variable Capital Gain significant effect on stock trading volume. 2). Dividend variable has no significant effect on stock prices. 3). The variables of Capital Gain and Dividend together (simultaneously) have no significant effect on the Volume of Stock Trading in Financial Companies during the 2016- 2020 period

Twisting 4-manifolds along RP^2

We prove that the Dolgachev surface E(1)_{2,3} (which is an exotic copy of the elliptic surface E(1)=CP^2 # 9(-CP^2)) can be obtained from E(1) by twisting along a simple "plug", in particular it can be obtained from E(1) by twisting along an RP^2.Comment: 5 papes, 5 figures.

Homologous Non-isotopic Symplectic Tori in Homotopy Rational Elliptic Surfaces

Let E(1)_K denote the closed 4-manifold that is homotopy equivalent (hence homeomorphic) to the rational elliptic surface E(1) and is obtained by performing Fintushel-Stern knot surgery on E(1) using a knot K in S^3. We construct an infinite family of homologous non-isotopic symplectic tori representing a primitive homology class in E(1)_K when K is any nontrivial fibred knot in S^3. We also show how these tori can be non-isotopically embedded as homologous symplectic submanifolds in other symplectic 4-manifolds.Comment: 8 pages, 2 figure
