Traversable Wormholes in Gravity
Nisha Godani, Gauranga C. Samanta
In this work, the study of traversable wormholes in gravity with the function , where and are arbitrary constants, is taken into account. The shape func…
Field Theories on Null Manifolds
Arjun Bagchi, Rudranil Basu, Aditya Mehra +1
We argue that generic field theories defined on null manifolds should have an emergent BMS or conformal Carrollian structure. We then focus on a simple interacting conformal Carrol…
Supersymmetric Localization on dS: Sum over topologies
Rudranil Basu, Augniva Ray
We find the exact quantum gravity partition function on the static patch of 3d de Sitter spacetime. We have worked in the Chern Simons Formulation of 3d Gravity. To obtain a non-pe…
Performance evaluation of deep neural networks for forecasting time-series with multiple structural breaks and high volatility
Rohit Kaushik, Shikhar Jain, Siddhant Jain +1
The problem of automatic and accurate forecasting of time-series data has always been an interesting challenge for the machine learning and forecasting community. A majority of the…
Static Traversable Wormholes in Gravity
Nisha Godani, Gauranga C. Samanta
Traversable wormholes, studied by Morris and Thorne \cite{Morris1} in general relativity, are investigated in this research paper in gravity by introducing a new form of n…
Physical Parameters for Stable Models
Gauranga C Samanta, Nisha Godani
Nojiri \& Odintsov \cite{noj1} and Hu \& Sawicki \cite{hu} have studied non-linear functions in modified gravity that explain the cosmic acceleration without cosmological constant,…
Validation of Energy Conditions in Wormhole Geometry within Viable Gravity
Gauranga C Samanta, Nisha Godani
In this work, wormholes, tunnel like structures introduced by Morris \& Thorne \cite{Morris95}, are explored within the framework of gravity. Using the shape function $b(r)=…
Wormhole Modeling Supported by Non-Exotic Matter
Gauranga C. Samanta, Nisha Godani
In the present paper, the modelling of traversale wormholes, proposed by Morris \& Thorne \cite{morris1}, is performed within the gravity with particular viable case $f(R)=R…
Non violation of energy conditions in wormholes modelling
Nisha Godani, Gauranga C. Samanta
Morris \& Thorne \cite{morris1} proposed geometrical objects called traversable wormholes that act as bridges in connecting two spacetimes or two different points of the same space…
Evolution of Novel Activation Functions in Neural Network Training with Applications to Classification of Exoplanets
Snehanshu Saha, Nithin Nagaraj, Archana Mathur +1
We present analytical exploration of novel activation functions as consequence of integration of several ideas leading to implementation and subsequent use in habitability classifi…
Stability analysis for cosmological models in gravity using dynamical system analysis
Parth Shah, Gauranga C. Samanta
Modified gravity theories have received increased attention lately to understand the late time acceleration of the universe. This viewpoint essentially modifies the geometric compo…
Core and Core-EP Inverses of Tensors
Jajati Kesahri Sahoo, Ratikanta Behera, Predrag S. Stanimirovic +2
Specific definitions of the core and core-EP inverses of complex tensors are introduced. Some characterizations, representations and properties of the core and core-EP inverses are…
Convolutional Feature Extraction and Neural Arithmetic Logic Units for Stock Prediction
Shangeth Rajaa, Jajati Keshari Sahoo
Stock prediction is a topic undergoing intense study for many years. Finance experts and mathematicians have been working on a way to predict the future stock price so as to decide…
Further results on the Drazin inverse of even-order tensors
Ratikanta Behera, Ashish Kumar Nandi, Jajati Keshari Sahoo
The notion of the Drazin inverse of an even-order tensor with the Einstein product was introduced, very recently [J. Ji and Y. Wei. Comput. Math. Appl., 75(9), (2018), pp. 3402-341…
Malware Detection using Machine Learning and Deep Learning
Hemant Rathore, Swati Agarwal, Sanjay K. Sahay +1
Research shows that over the last decade, malware has been growing exponentially, causing substantial financial losses to various organizations. Different anti-malware companies ha…
Generalized Inverses of Boolean Tensors via Einstein Product
Ratikanta Behera, Jajati Keshari Sahoo
Applications of the theory and computations of boolean matrices are of fundamental importance to study a variety of discrete structural models. But the increasing ability of data c…
On the Ca-strong 1991bg-like type Ia supernova 2016hnk: evidence for a Chandrasekhar-mass explosion
Lluís Galbany, Chris Ashall, Peter Hoeflich +46
We present a comprehensive dataset of optical and near-infrared photometry and spectroscopy of type~Ia supernova (SN) 2016hnk, combined with integral field spectroscopy (IFS) of it…

Karim Mosani, Gauranga C. Samanta
Gravitational collapse of a spherically symmetric homogeneous perfect barotropic fluid with linear as well as polytropic type Equation of State (EoS) has been investigated in the f…
Determining Star Formation Thresholds from Observations
Shivan Khullar, Mark R. Krumholz, Christoph Federrath +1
Most gas in giant molecular clouds is relatively low-density and forms star inefficiently, converting only a small fraction of its mass to stars per dynamical time. However, star f…
