    • Examples of varieties with index one on C1 fields 

      Dan, A.; Kaur, I. (2019-04-16)
      Let K be the fraction field of a Henselian discrete valuation ring with algebraically closed residue field k. In this article we give a sufficient criterion for a projective variety over such a field to have index 1.
    • Neron models of intermediate Jacobians associated to moduli spaces 

      Dan, A.; Kaur, I. (2019-12-01)
      Let $\pi_1:\mathcal{X} \to \Delta$ be a flat family of smooth, projective curves of genus $g \ge 2$, degenerating to an irreducible nodal curve $X_0$ with exactly one node. Fix an invertible sheaf $\mathcal{L}$ on $\mathcal{X}$ ...
    • A note on the determinant map 

      Dan, A.; Kaur, I. (2017-01-10)
      Classically, there exists a determinant map from the moduli space of semi-stable sheaves on a smooth, projective variety to the Picard scheme. Unfortunately, if the underlying variety is singular, then such a map does not ...
    • RandomFront 2.3 A physical parametrisation of fire-spotting for operational fire spread models: Implementation in WRF-Sfire and response analysis with LSFire+ 

      Trucchia, A.; Egorova, V.; Butenko, A.; Kaur, I.; Pagnini, G. (2018-12)
      Fire-spotting is often responsible for a dangerous flare up in the wildfire and causes secondary ignitions isolated from the primary fire zone leading to perilous situations. The main aim of the present research to provide ...
    • A specialization property of index 

      Dan, A.; Kaur, I. (2017-01-10)
      In [Kol13] Kollár defined $i$-th index of a proper scheme over a field. In this note we study how index behaves under specialization, in any characteristic.
    • Turbulence and fire-spotting effects into wild-land fire simulators 

      Kaur, I.; Mentrelli, A.; Bosseur, F.; Filippi, J.-B.; Pagnini, G. (2016-01-01)
      This paper presents a mathematical approach to model the effects and the role of phenomena with random nature such as turbulence and fire-spotting into the existing wildfire simulators. The formulation proposes that the ...
    • Wildfire propagation modelling 

      Pagnini, G.; Egorova, V.; Trucchia, A.; Mentrelli, A.; Kaur, I. (2018)
      Wildfires are a concrete problem with a strong impact on human life, property and the environment, because they cause disruption and are an important source of pollutants. Climate change and ...
