A necessary condition for the existence of solutions of singular linear-quadratic vector equations
Rishikesh Yadav, Axel Flinth
We study the existence of solutions for systems of linear-quadratic vector equations with singular linear parts. We derive a sufficient condition for small right hand sides.

A Stancu Variant of Szász-Mirakjan-Kantorovich type Operators: Approximation Properties and Asymptotic Analysis
Rishikesh Yadav, Ramakanta Meher, Vishnu Narayan Mishra
This paper investigates the generalized version of the Stancu variant Szász-Mirakjan Kantorovich type operators. We determine the order of approximation in terms of modulus of cont…

Statistics of extremes for natural hazards: landslides and earthquakes
Rishikesh Yadav, Luigi Lombardo, Raphaël Huser
In this chapter, we illustrate the use of split bulk-tail models and subasymptotic models motivated by extreme-value theory in the context of hazard assessment for earthquake-induc…
