Given a Henselian and Japanese discrete valuation ring $A$ flat projective $A$-scheme $X$, we follow the approach of Biswas-dos Santos to introduce full subcategory coherent modules on $X$ which is then shown be Tannakian. We prove that, under normality generic fibre, associated affine group pro-finite in strong sense (so that its functions Mittag-Leffler $A$-module) it classifies finite torsor...

We consider the nonlinear Neumann problem for fully elliptic PDEs on a quadrant. establish comparison theorem viscosity sub- and supersolutions of problem. The crucial argument in proof is to build $C^{1,1}$ test function which takes care boundary condition. A similar has been treated general $n$-dimensional orthant by Biswas et al. [SIAM J. Control Optim., 55 (2017), pp. 365--396], where funct...

V.S Naipaul is acknowledged as one of the most talented writers dealing with postcolonial themes for his fictions. As a Nobel Prize winner author, he has written number fictions such A House Mr Biswas (1961), Bend in River (1979), Miguel Street (1959), An Area Darkness (1964), In Free State (1971), The Mimic Men (1967), India: Million Mutinies Now (1990) and so on. article presents review thoro...

This research uses a novel analytical method known as the modified Extended Direct Algebraic Method (mEDAM) to explore families of soliton solutions for complex structured Coupled Fractional Biswas–Arshed Model (CFBAM) in Birefringent Fibers. The (DAM) is extended by mEDAM’s methodology compute more that would otherwise be difficult acquire. We use this derive several and examine their characte...

In prior work (Biswas & Chatterjee 2014 Proc. R. Soc. A 470, 20130817 (doi:10.1098/rspa.2013.0817)), we developed a six-state hysteresis model from a high-dimensional frictional system. Here, we use a more intuitively appealing frictional system that resembles one studied earlier by Iwan. The basis functions now have simple analytical description. The number of states required decreases further...

BACKGROUND The genus Platythomisus Doleschall, 1859 presently comprises 13 valid species, nine known from Africa and four from Asia. All Platythomisus species are known from females only, except P. jucundus Thorell, 1894 and P. sudeepi Biswas, 1977 from both sexes and P. quadrimaculatus from juvenile. Only, P. sudeepi was reported from India. NEW INFORMATION Platythomisus octomaculatus (C. L....

OBJECTIVE To evaluate the efficacy of Ormeloxifene for dysfunctional menorrhagia (DUB). METHODS Eighty five women aged 30 to 51 years who attended the outpatient gynecology department with complaint of heavy menstrual flow were recruited for the study. Ormeloxifene (60 mg)was given orally twice a week for first 12 weeks and then once a week for up to next 12 weeks. Menstrual blood loss measurem...
