Michael Roberts (mathematician)
Michael Roberts (18 April 1817 – 4 October 1882), was an Irish mathematician and academic of Trinity College, Dublin (TCD), who served as Erasmus Smith's Professor of Mathematics there 1862-1879. Life Roberts was born into a well-established landed gentry family in County Cork, whose ancestors had settled there from Kent about 1630. His mother was of Scottish origins, descended from the Colonel Stewart who was governor of Edinburgh Castle and took part in the Jacobite rising of 1715.W. F. Sedgwick, revised by Julia Tompson, "Roberts, Michael (1817–1882), mathematician", in '' Oxford Dictionary of National Biography'', published online 23 September 2004, accessed 22 April 2019 Roberts had a twin brother, William, and they were educated together at Midleton School, Cork. A portrait is reported of Roberts and his twin brother at the age of sixteen. He entered TCD in 1833. He was awarded a classical scholarship in 1836, but studied mostly under the notable mathematician and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People Educated At Midleton College
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Alumni Of Trinity College Dublin
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating ( Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from the ...

1882 Deaths
Year 188 (CLXXXVIII) was a leap year starting on Monday of the Julian calendar. At the time, it was known in the Roman Empire as the Year of the Consulship of Fuscianus and Silanus (or, less frequently, year 941 ''Ab urbe condita''). The denomination 188 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Publius Helvius Pertinax becomes pro-consul of Africa from 188 to 189. Japan * Queen Himiko (or Shingi Waō) begins her reign in Japan (until 248).

Merrion Square
Merrion Square () is a Georgian garden square on the southside of Dublin city centre. History The square was laid out in 1752 by the estate of Viscount FitzWilliam and was largely complete by the beginning of the 19th century. The demand for such Georgian townhouse residences south of the River Liffey had been fuelled by the decision of the then Earl of Kildare (later the Duke of Leinster) to build his Dublin home on the then undeveloped southside. He constructed the largest aristocratic residence in Dublin, Leinster House, second only to Dublin Castle. As a result of this construction, three new residential squares appeared on the Southside: Merrion Square (facing the garden front of Leinster House), St Stephen's Green, and the smallest and last to be built, Fitzwilliam Square. Aristocrats, bishops and the wealthy sold their northside townhouses and migrated to the new southside developments. Legacy All the original 18th century properties in Merrion Square have survived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abelian Function
In mathematics, particularly in algebraic geometry, complex analysis and algebraic number theory, an abelian variety is a projective algebraic variety that is also an algebraic group, i.e., has a group law that can be defined by regular functions. Abelian varieties are at the same time among the most studied objects in algebraic geometry and indispensable tools for much research on other topics in algebraic geometry and number theory. An abelian variety can be defined by equations having coefficients in any field; the variety is then said to be defined ''over'' that field. Historically the first abelian varieties to be studied were those defined over the field of complex numbers. Such abelian varieties turn out to be exactly those complex tori that can be embedded into a complex projective space. Abelian varieties defined over algebraic number fields are a special case, which is important also from the viewpoint of number theory. Localization techniques lead naturally fr ...

Invariant (mathematics)
In mathematics, an invariant is a property of a mathematical object (or a class of mathematical objects) which remains unchanged after operations or transformations of a certain type are applied to the objects. The particular class of objects and type of transformations are usually indicated by the context in which the term is used. For example, the area of a triangle is an invariant with respect to isometries of the Euclidean plane. The phrases "invariant under" and "invariant to" a transformation are both used. More generally, an invariant with respect to an equivalence relation is a property that is constant on each equivalence class. Invariants are used in diverse areas of mathematics such as geometry, topology, algebra and discrete mathematics. Some important classes of transformations are defined by an invariant they leave unchanged. For example, conformal maps are defined as transformations of the plane that preserve angles. The discovery of invariants is an important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Covariant (invariant Theory)
In invariant theory, a branch of algebra, given a group ''G'', a covariant is a ''G''-equivariant polynomial map V \to W between linear representations ''V'', ''W'' of ''G''. It is a generalization of a classical convariant, which is a homogeneous polynomial map from the space of binary ''m''-forms to the space of binary ''p''-forms (over the complex numbers) that is SL_2(\mathbb)-equivariant. See also *module of covariants * Invariant of a binary form#Terminology *Transvectant In mathematical invariant theory, a transvectant is an invariant formed from ''n'' invariants in ''n'' variables using Cayley's Ω process.

Algebraic Equation
In mathematics, an algebraic equation or polynomial equation is an equation of the form :P = 0 where ''P'' is a polynomial with coefficients in some field, often the field of the rational numbers. For many authors, the term ''algebraic equation'' refers only to ''univariate equations'', that is polynomial equations that involve only one variable. On the other hand, a polynomial equation may involve several variables. In the case of several variables (the ''multivariate'' case), the term ''polynomial equation'' is usually preferred to ''algebraic equation''. For example, :x^5-3x+1=0 is an algebraic equation with integer coefficients and :y^4 + \frac - \frac + xy^2 + y^2 + \frac = 0 is a multivariate polynomial equation over the rationals. Some but not all polynomial equations with rational coefficients have a solution that is an algebraic expression that can be found using a finite number of operations that involve only those same types of coefficients (that is, can be solved alg ...
