Rational points in the moduli space of genus two
We build a database of genus 2 curves defined over which contains
all curves with minimal absolute height , all curves with moduli
height , and all curves with extra automorphisms in
standard form defined over with height .
For each isomorphism class in the database, an equation over its minimal field
of definition is provided, the automorphism group of the curve, Clebsch and
Igusa invariants. The distribution of rational points in the moduli space
for which the field of moduli is a field of definition is
discussed and some open problems are presented
Emerging markets portfolio creating a Latin American portfolio peruvian case study
The case study seeks to identify the most important issues encountered in developing a new portfolio in a Latin America country, exploring several alternatives which include not only stock and sovereign bonds but also more sophisticate products such as American Depositary Receipt (ADR) or Exchange Traded Fund (ETF) from emerging countries, and determine what are the risks involved in the process following not only Basil III standards, but also the local best practice recommend by the local regulators. The study at the beginning used historical information (normal distribution formulas) of several equities and bonds (n = 142) and then selected five Peruvian instruments (one of this involved at least 25 equities, N = 5, n = 30) and then other 30 (one of this include an ETF, N = 30, n = 55) in order to determine the best return and risk combination for an emerging market portfolio. Besides, the additional objective is to examine and introduce the reader in some statistics formulas used in finance and risk management. Senior management must evaluate the issues associated with the new portfolio and strategy developed
Credit information in emerging markets: the rating agencies and credit risk reports, Peruvian experience
This paper seeks to develop a literature review within the main aspects of credit information in emerging markets, important aspect considering that several companies, including the small enterprises, are looking forward to “go” to capital markets. Thus, we will analyze the role of rating agencies and credit bureaus (credit risk report) in the Peruvian market, considering the current state of economic growth that comes through and, the potential of capital market that comes with MILA (Integrated Latin American Market). Besides, this information will become relevant in the following months, because the actual financial crisis in several countries all over the world (focus in Europe, but it could move to some BRICS – Brazil, Russia, India, China and South Africa – or Latam Countries) has generated a new map in “rating scores” (Note 1) so the questions that we tried to answer is if this unique change is relevant? Or it should be complemented in order to have a significant impact in the market and for the investors
Agricultural eco-efficiency and water footprint- A case study of fifteen crops in the Chupaca province of Peru
The water footprint is an indicator of the impact of water use from its formation to its final destination. Agricultural eco-efficiency measures the efficient use of resources or materials available for crop production. Water's economic productivity analyses a product's efficient value as per its water supply and commercial value. The present research aimed to determine and relate the water footprint, economic productivity of water and agricultural eco-efficiency of 15 crops in the province of Chupaca - Peru. Georeferencing material was used for the delimitation of agricultural species, CROPWAT 8.0, CLIMWAT8.0, ArcGis 10.5 software, mathematical equations for the water footprint, agricultural eco-efficiency (Data Envelopment Analysis (DEA)) and economic productivity of water. The Total water footprint (TWF) of the fifteen crops was 1718237.01 m3/ton, likewise the BlueWF > GreenWF > GreyWF. In their economic outputs, gross value of production (GVP) > agricultural production (Ag-p) > economic rent agricultural (ERA) was verified. In environmental costs, water consumption that meets the needs of crops (Wc-Ag) > consumption of phytosanitary products (C-fly) > fertilizer consumption (C-fe) was determined. The average Agricultural eco-efficiency (Ag-Eec) and Economic water productivity (Ewp) were 89.8% and 0.046 PEN/m3 respectively. Statistical analysis between Ewp and Ag-Eec was rho = 0.18, t-test = 0.66 < 2.16 (α = 0.05; bilateral), and the correlation indicated that both activities are independent. The environmental costs and economic outputs of agricultural eco-efficiency did not influence the economic value of water.
Analyzing solid waste landfills using satellite imagery and designing new landfill reception areas
Solid waste disposal is important for environmental management for good quality of life in urban cities. Among them is the final disposal of waste in landfills. Landfills can receive tons of waste, but they must be far away from natural resources and urban areas. The research aimed to analyze the physical and biological conditions and design a geolocation map of new sanitary landfills in three urban cities in Peru (Chilca, El Tambo and Huancayo). Landsat 8 OLI/TIRS satellite imagery was used to analyze the physical (LST and Methane) and biological (NDVI and SAVI) conditions of the landfills. The geolocation of the landfills was analyzed through the relationship, intersection and discrimination between their surface criteria (soil type, current use, geology and physiography) and climatic factors (temperature, humidity and precipitation). The physical and biological conditions of the landfills were: CH4: Chilca 8.33g > Huancayo 4.76g > El-Tambo 3.17g; SAVI: Chilca 0.61 > El Tambo 0.54 > Huancayo 0.51; LST: Huancayo 26.15°C > Chilca 24.03°C > El Tambo 22.75°C; NDVI: Chilca 0.85 > Huancayo 0.81 > El Tambo 0.8. In the three cities, "natural grasslands" were considered suitable land for the new solid waste landfill site. The multiple relationship, intersection, and discrimination of surface criteria and climatic factors were categorized into five types of sustainable geolocation (very appropriate > appropriate > moderately adequate > less appropriate > inappropriate) for new solid waste landfills. It was very important to discount the influence areas (rivers and lagoons) to avoid damaging the natural resources.
