Equivariant Crossed Modules and Cohomology of Groups with Operators
In this paper we study equivariant crossed modules in its link with strict
graded categorical groups. The resulting Schreier theory for equivariant group
extensions of the type of an equivariant crossed module generalizes both the
theory of group extensions of the type of a crossed module and the one of
equivariant group extensions.Comment: 20 pag
Crossed bimodules over rings and Shukla cohomology
In this paper we present some applications of Ann-category theory to
classification of crossed bimodules over rings, classification of
ring extensions of the type of a crossed bimodule
The nexus among green financial development and renewable energy: investment in the wake of the Covid19 pandemic
Environmental protection has become a significant issue around
the globe. The extensive use of renewable energy and green
finance is considered as the solution to this dramatic issue, especially in the Covid-19 lockdown. To answer this demand, the present study examines the impact of green financial development
such as green credit, green investment, and green securities
along with corporate social responsibility (CSR) in reporting
renewable energy investment based on evidence from an emerging economy. Economic growth was used as the control variable
of the study. The data was gathered from the central bank and
World Development Indicators (WDI) from 1976 to 2020. The error
correction model (ECM) was used to test the nexus among the
variables. The findings revealed that green credit, green investment, and green securities along with CSR reporting and economic growth have a significant positive nexus with renewable
energy investment in the selected emerging economy. These outcomes are helpful for new arrivals to investigate this area in the
future along with regulators who want to formulate policies
related to green finance and renewable energy usage and investment in the context of emerging and developing countries
Analyzing the Determinants of Services Trade Flow between Vietnam and European Union: Gravity Model Approach
This paper aims at analyzing the determinants of services trade flows between Vietnam and European Union. In this respect, a gravity model has been estimated with panel data and pooled, random and fixed effect estimation covering the period of ten years from 2002 to 2011 for total services trade, services exports and services imports between Vietnam and European Union separately. The estimated results on total services trade indicate that bilateral services trade flows between Vietnam and its European partner countries are mainly affected by GDP per capita gap between Vietnam and partner countries, population of partner countries, real effective exchange rate, colonial relationship and being former members of CMEA
